+  (default 1)
+  Use 'init=0' to bypass initializing the chip.
+  Try this if your computer crashes when you load the module.
+
+* force_subclients=bus,caddr,saddr,saddr
+  This is used to force the i2c addresses for subclients of
+  a certain chip. Example usage is `force_subclients=0,0x2f,0x4a,0x4b'
+  to force the subclients of chip 0x2f on bus 0 to i2c addresses
+  0x4a and 0x4b.
+
+
+Description
+-----------
+
+This driver implements support for the Winbond W83792AD/D.
+
+Detection of the chip can sometimes be foiled because it can be in an
+internal state that allows no clean access (Bank with ID register is not
+currently selected). If you know the address of the chip, use a 'force'
+parameter; this will put it into a more well-behaved state first.
+
+The driver implements three temperature sensors, seven fan rotation speed
+sensors, nine voltage sensors, and two automatic fan regulation
+strategies called: Smart Fan I (Thermal Cruise mode) and Smart Fan II.
+Automatic fan control mode is possible only for fan1-fan3. Fan4-fan7 can run
+synchronized with selected fan (fan1-fan3). This functionality and manual PWM
+control for fan4-fan7 is not yet implemented.
+
+Temperatures are measured in degrees Celsius and measurement resolution is 1
+degC for temp1 and 0.5 degC for temp2 and temp3. An alarm is triggered when
+the temperature gets higher than the Overtemperature Shutdown value; it stays
+on until the temperature falls below the Hysteresis value.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. Fan
+readings can be divided by a programmable divider (1, 2, 4, 8, 16, 32, 64 or
+128) to give the readings more range or accuracy.
+
+Voltage sensors (also known as IN sensors) report their values in millivolts.
+An alarm is triggered if the voltage has crossed a programmable minimum
+or maximum limit.
+
+Alarms are provided as output from "realtime status register". Following bits
+are defined:
+
+bit - alarm on:
+0  - in0
+1  - in1
+2  - temp1
+3  - temp2
+4  - temp3
+5  - fan1
+6  - fan2
+7  - fan3
+8  - in2
+9  - in3
+10 - in4
+11 - in5
+12 - in6
+13 - VID change
+14 - chassis
+15 - fan7
+16 - tart1
+17 - tart2
+18 - tart3
+19 - in7
+20 - in8
+21 - fan4
+22 - fan5
+23 - fan6
+
+Tart will be asserted while target temperature cannot be achieved after 3 minutes
+of full speed rotation of corresponding fan.
+
+In addition to the alarms described above, there is a CHAS alarm on the chips
+which triggers if your computer case is open (This one is latched, contrary
+to realtime alarms).
+
+The chips only update values each 3 seconds; reading them more often will
+do no harm, but will return 'old' values.
+
+
+W83792D PROBLEMS
+----------------
+Known problems:
+	- This driver is only for Winbond W83792D C version device, there
+	  are also some motherboards with B version W83792D device. The
+	  calculation method to in6-in7(measured value, limits) is a little
+	  different between C and B version. C or B version can be identified
+	  by CR[0x49h].
+	- The function of vid and vrm has not been finished, because I'm NOT
+	  very familiar with them. Adding support is welcome.
+ 	- The function of chassis open detection needs more tests.
+	- If you have ASUS server board and chip was not found: Then you will
+	  need to upgrade to latest (or beta) BIOS. If it does not help please
+	  contact us.
+
+Fan control
+-----------
+
+Manual mode
+-----------
+
+Works as expected. You just need to specify desired PWM/DC value (fan speed)
+in appropriate pwm# file.
+
+Thermal cruise
+--------------
+
+In this mode, W83792D provides the Smart Fan system to automatically control
+fan speed to keep the temperatures of CPU and the system within specific
+range. At first a wanted temperature and interval must be set. This is done
+via thermal_cruise# file. The tolerance# file serves to create T +- tolerance
+interval. The fan speed will be lowered as long as the current temperature
+remains below the thermal_cruise# +- tolerance# value. Once the temperature
+exceeds the high limit (T+tolerance), the fan will be turned on with a
+specific speed set by pwm# and automatically controlled its PWM duty cycle
+with the temperature varying. Three conditions may occur:
+
+(1) If the temperature still exceeds the high limit, PWM duty
+cycle will increase slowly.
+
+(2) If the temperature goes below the high limit, but still above the low
+limit (T-tolerance), the fan speed will be fixed at the current speed because
+the temperature is in the target range.
+
+(3) If the temperature goes below the low limit, PWM duty cycle will decrease
+slowly to 0 or a preset stop value until the temperature exceeds the low
+limit. (The preset stop value handling is not yet implemented in driver)
+
+Smart Fan II
+------------
+
+W83792D also provides a special mode for fan. Four temperature points are
+available. When related temperature sensors detects the temperature in preset
+temperature region (sf2_point@_fan# +- tolerance#) it will cause fans to run
+on programmed value from sf2_level@_fan#. You need to set four temperatures
+for each fan.

 General Remarks
 ---------------
 
-A typical application will require that the EEPROMs be programmed once and
-never altered afterwards.
+Valid addresses for the MAX6875 are 0x50 and 0x52.
+Valid addresses for the MAX6874 are 0x50, 0x52, 0x54 and 0x56.
+The driver does not probe any address, so you must force the address.
+
+Example:
+$ modprobe max6875 force=0,0x50
+
+The MAX6874/MAX6875 ignores address bit 0, so this driver attaches to multiple
+addresses.  For example, for address 0x50, it also reserves 0x51.
+The even-address instance is called 'max6875', the odd one is 'max6875 subclient'.
+
+
+Programming the chip using i2c-dev
+----------------------------------
+
+Use the i2c-dev interface to access and program the chips.
+Reads and writes are performed differently depending on the address range.
+
+The configuration registers are at addresses 0x00 - 0x45.
+Use i2c_smbus_write_byte_data() to write a register and
+i2c_smbus_read_byte_data() to read a register.
+The command is the register number.
+
+Examples:
+To write a 1 to register 0x45:
+  i2c_smbus_write_byte_data(fd, 0x45, 1);
+
+To read register 0x45:
+  value = i2c_smbus_read_byte_data(fd, 0x45);
+
+
+The configuration EEPROM is at addresses 0x8000 - 0x8045.
+The user EEPROM is at addresses 0x8100 - 0x82ff.
+
+Use i2c_smbus_write_word_data() to write a byte to EEPROM.
+
+The command is the upper byte of the address: 0x80, 0x81, or 0x82.
+The data word is the lower part of the address or'd with data << 8.
+  cmd = address >> 8;
+  val = (address & 0xff) | (data << 8);
+
+Example:
+To write 0x5a to address 0x8003:
+  i2c_smbus_write_word_data(fd, 0x80, 0x5a03);
+
+
+Reading data from the EEPROM is a little more complicated.
+Use i2c_smbus_write_byte_data() to set the read address and then
+i2c_smbus_read_byte() or i2c_smbus_read_i2c_block_data() to read the data.
+
+Example:
+To read data starting at offset 0x8100, first set the address:
+  i2c_smbus_write_byte_data(fd, 0x81, 0x00);
+
+And then read the data
+  value = i2c_smbus_read_byte(fd);
+
+  or
+
+  count = i2c_smbus_read_i2c_block_data(fd, 0x84, buffer);
+
+The block read should read 16 bytes.
+0x84 is the block read command.
+
+See the datasheet for more details.

-     'probe', but not the 'force' lists.
-
-Also used is a list of pointers to sensors_force_data structures:
-   force_data: insmod parameters. A list, ending with an element of which
-     the force field is NULL.
-     Each element contains the type of chip and a list of pairs.
-     The first value is a bus number (SENSORS_ISA_BUS for the ISA bus, 
-     -1 for any I2C bus), the second is the address. 
-     These are automatically translated to insmod variables of the form
-     force_foo.
-
-So we have a generic insmod variabled `force', and chip-specific variables
-`force_CHIPNAME'.
-
-Fortunately, as a module writer, you just have to define the `normal_i2c' 
-and `normal_isa' parameters, and define what chip names are used. 
-The complete declaration could look like this:
-  /* Scan i2c addresses 0x37, and 0x48 to 0x4f */
-  static unsigned short normal_i2c[] = { 0x37, 0x48, 0x49, 0x4a, 0x4b, 0x4c,
-                                         0x4d, 0x4e, 0x4f, I2C_CLIENT_END };
-  /* Scan ISA address 0x290 */
-  static unsigned int normal_isa[] = {0x0290,SENSORS_ISA_END};
-
-  /* Define chips foo and bar, as well as all module parameters and things */
-  SENSORS_INSMOD_2(foo,bar);
-
-If you have one chip, you use macro SENSORS_INSMOD_1(chip), if you have 2
-you use macro SENSORS_INSMOD_2(chip1,chip2), etc. If you do not want to
-bother with chip types, you can use SENSORS_INSMOD_0.
-
-A enum is automatically defined as follows:
-  enum chips { any_chip, chip1, chip2, ... }

+0. Introduction
+------------ -----   -----       ----       ---       --         -     
+
+This document provides a brief overview of the features supported by the 
+IPW2100 driver project.  The main project website, where the latest 
+development version of the driver can be found, is:
+
+	http://ipw2100.sourceforge.net
+
+There you can find the not only the latest releases, but also information about
+potential fixes and patches, as well as links to the development mailing list
+for the driver project.
+
+
+===========================
+1. Release 1.1.0 Current Supported Features
+---------------------------     
+- Managed (BSS) and Ad-Hoc (IBSS)
+- WEP (shared key and open)
+- Wireless Tools support 
+- 802.1x (tested with XSupplicant 1.0.1)
+
+Enabled (but not supported) features:
+- Monitor/RFMon mode
+- WPA/WPA2
+
+The distinction between officially supported and enabled is a reflection
+on the amount of validation and interoperability testing that has been
+performed on a given feature.
+
+
+===========================
+2. Command Line Parameters
+---------------------------     
+
+If the driver is built as a module, the following optional parameters are used
+by entering them on the command line with the modprobe command using this
+syntax:
+
+	modprobe ipw2100 [<option>=<VAL1><,VAL2>...]
+
+For example, to disable the radio on driver loading, enter:
+
+	modprobe ipw2100 disable=1
+
+The ipw2100 driver supports the following module parameters:
+
+Name		Value		Example:
+debug		0x0-0xffffffff	debug=1024
+mode		0,1,2		mode=1   /* AdHoc */
+channel		int		channel=3 /* Only valid in AdHoc or Monitor */
+associate	boolean		associate=0 /* Do NOT auto associate */
+disable		boolean		disable=1 /* Do not power the HW */
+
+
+===========================
+3. Sysfs Helper Files
+---------------------------     
+
+There are several ways to control the behavior of the driver.  Many of the 
+general capabilities are exposed through the Wireless Tools (iwconfig).  There
+are a few capabilities that are exposed through entries in the Linux Sysfs.
+
+
+----- Driver Level ------
+For the driver level files, look in /sys/bus/pci/drivers/ipw2100/
+
+  debug_level  
+	
+	This controls the same global as the 'debug' module parameter.  For 
+        information on the various debugging levels available, run the 'dvals'
+	script found in the driver source directory.
+
+	NOTE:  'debug_level' is only enabled if CONFIG_IPW2100_DEBUG is turn
+	       on.
+
+----- Device Level ------
+For the device level files look in
+	
+	/sys/bus/pci/drivers/ipw2100/{PCI-ID}/
+
+For example:
+	/sys/bus/pci/drivers/ipw2100/0000:02:01.0
+
+For the device level files, see /sys/bus/pci/drivers/ipw2100:
+
+  rf_kill
+	read - 
+	0 = RF kill not enabled (radio on)
+	1 = SW based RF kill active (radio off)
+	2 = HW based RF kill active (radio off)
+	3 = Both HW and SW RF kill active (radio off)
+	write -
+	0 = If SW based RF kill active, turn the radio back on
+	1 = If radio is on, activate SW based RF kill
+
+	NOTE: If you enable the SW based RF kill and then toggle the HW
+  	based RF kill from ON -> OFF -> ON, the radio will NOT come back on
+
+
+===========================
+4. Radio Kill Switch
+---------------------------
+Most laptops provide the ability for the user to physically disable the radio.
+Some vendors have implemented this as a physical switch that requires no
+software to turn the radio off and on.  On other laptops, however, the switch
+is controlled through a button being pressed and a software driver then making
+calls to turn the radio off and on.  This is referred to as a "software based
+RF kill switch"
+
+See the Sysfs helper file 'rf_kill' for determining the state of the RF switch
+on your system.
+
+
+===========================
+5. Dynamic Firmware
+---------------------------     
+As the firmware is licensed under a restricted use license, it can not be 
+included within the kernel sources.  To enable the IPW2100 you will need a 
+firmware image to load into the wireless NIC's processors.
+
+You can obtain these images from <http://ipw2100.sf.net/firmware.php>.
+
+See INSTALL for instructions on installing the firmware.
+
+
+===========================
+6. Power Management
+---------------------------     
+The IPW2100 supports the configuration of the Power Save Protocol 
+through a private wireless extension interface.  The IPW2100 supports 
+the following different modes:
+
+	off	No power management.  Radio is always on.
+	on	Automatic power management
+	1-5	Different levels of power management.  The higher the 
+		number the greater the power savings, but with an impact to 
+		packet latencies. 
+
+Power management works by powering down the radio after a certain 
+interval of time has passed where no packets are passed through the 
+radio.  Once powered down, the radio remains in that state for a given 
+period of time.  For higher power savings, the interval between last 
+packet processed to sleep is shorter and the sleep period is longer.
+
+When the radio is asleep, the access point sending data to the station 
+must buffer packets at the AP until the station wakes up and requests 
+any buffered packets.  If you have an AP that does not correctly support 
+the PSP protocol you may experience packet loss or very poor performance 
+while power management is enabled.  If this is the case, you will need 
+to try and find a firmware update for your AP, or disable power 
+management (via `iwconfig eth1 power off`)
+
+To configure the power level on the IPW2100 you use a combination of 
+iwconfig and iwpriv.  iwconfig is used to turn power management on, off, 
+and set it to auto.
+
+	iwconfig eth1 power off    Disables radio power down
+	iwconfig eth1 power on     Enables radio power management to 
+				   last set level (defaults to AUTO)
+	iwpriv eth1 set_power 0    Sets power level to AUTO and enables 
+				   power management if not previously 
+				   enabled.
+	iwpriv eth1 set_power 1-5  Set the power level as specified, 
+				   enabling power management if not 
+				   previously enabled.
+
+You can view the current power level setting via:
+	
+	iwpriv eth1 get_power
+
+It will return the current period or timeout that is configured as a string
+in the form of xxxx/yyyy (z) where xxxx is the timeout interval (amount of
+time after packet processing), yyyy is the period to sleep (amount of time to 
+wait before powering the radio and querying the access point for buffered
+packets), and z is the 'power level'.  If power management is turned off the
+xxxx/yyyy will be replaced with 'off' -- the level reported will be the active
+level if `iwconfig eth1 power on` is invoked.

+1.   Introduction
+-----------------------------------------------
+The following sections attempt to provide a brief introduction to using 
+the Intel(R) PRO/Wireless 2915ABG Driver for Linux.
+
+This document is not meant to be a comprehensive manual on 
+understanding or using wireless technologies, but should be sufficient 
+to get you moving without wires on Linux.
+
+For information on building and installing the driver, see the INSTALL
+file.
+
+
+1.1. Overview of Features
+-----------------------------------------------
+The current release (1.0.0) supports the following features:
+
++ BSS mode (Infrastructure, Managed)
++ IBSS mode (Ad-Hoc)
++ WEP (OPEN and SHARED KEY mode)
++ 802.1x EAP via wpa_supplicant and xsupplicant
++ Wireless Extension support 
++ Full B and G rate support (2200 and 2915)
++ Full A rate support (2915 only)
++ Transmit power control
++ S state support (ACPI suspend/resume)
++ long/short preamble support
+
+
+
+1.2. Command Line Parameters
+-----------------------------------------------
+
+Like many modules used in the Linux kernel, the Intel(R) PRO/Wireless 
+2915ABG Driver for Linux allows certain configuration options to be 
+provided as module parameters.  The most common way to specify a module 
+parameter is via the command line.  
+
+The general form is:
+
+% modprobe ipw2200 parameter=value
+
+Where the supported parameter are:
+
+  associate
+	Set to 0 to disable the auto scan-and-associate functionality of the
+	driver.  If disabled, the driver will not attempt to scan 
+	for and associate to a network until it has been configured with 
+	one or more properties for the target network, for example configuring 
+	the network SSID.  Default is 1 (auto-associate)
+	
+	Example: % modprobe ipw2200 associate=0
+
+  auto_create
+	Set to 0 to disable the auto creation of an Ad-Hoc network 
+	matching the channel and network name parameters provided.  
+	Default is 1.
+
+  channel
+	channel number for association.  The normal method for setting
+        the channel would be to use the standard wireless tools
+        (i.e. `iwconfig eth1 channel 10`), but it is useful sometimes
+	to set this while debugging.  Channel 0 means 'ANY'
+
+  debug
+	If using a debug build, this is used to control the amount of debug
+	info is logged.  See the 'dval' and 'load' script for more info on
+	how to use this (the dval and load scripts are provided as part 
+	of the ipw2200 development snapshot releases available from the 
+	SourceForge project at http://ipw2200.sf.net)
+
+  mode
+	Can be used to set the default mode of the adapter.  
+	0 = Managed, 1 = Ad-Hoc
+
+
+1.3. Wireless Extension Private Methods
+-----------------------------------------------
+
+As an interface designed to handle generic hardware, there are certain 
+capabilities not exposed through the normal Wireless Tool interface.  As 
+such, a provision is provided for a driver to declare custom, or 
+private, methods.  The Intel(R) PRO/Wireless 2915ABG Driver for Linux 
+defines several of these to configure various settings.
+
+The general form of using the private wireless methods is:
+
+	% iwpriv $IFNAME method parameters
+
+Where $IFNAME is the interface name the device is registered with 
+(typically eth1, customized via one of the various network interface
+name managers, such as ifrename)
+
+The supported private methods are:
+
+  get_mode
+	Can be used to report out which IEEE mode the driver is 
+	configured to support.  Example:
+	
+	% iwpriv eth1 get_mode
+	eth1	get_mode:802.11bg (6)
+
+  set_mode
+	Can be used to configure which IEEE mode the driver will 
+	support.  
+
+	Usage:
+	% iwpriv eth1 set_mode {mode}
+	Where {mode} is a number in the range 1-7:
+	1	802.11a (2915 only)
+	2	802.11b
+	3	802.11ab (2915 only)
+	4	802.11g 
+	5	802.11ag (2915 only)
+	6	802.11bg
+	7	802.11abg (2915 only)
+
+  get_preamble
+	Can be used to report configuration of preamble length.
+
+  set_preamble
+	Can be used to set the configuration of preamble length:
+
+	Usage:
+	% iwpriv eth1 set_preamble {mode}
+	Where {mode} is one of:
+	1	Long preamble only
+	0	Auto (long or short based on connection)
+	
+
+1.4. Sysfs Helper Files:
+-----------------------------------------------
+
+The Linux kernel provides a pseudo file system that can be used to 
+access various components of the operating system.  The Intel(R) 
+PRO/Wireless 2915ABG Driver for Linux exposes several configuration 
+parameters through this mechanism.
+
+An entry in the sysfs can support reading and/or writing.  You can 
+typically query the contents of a sysfs entry through the use of cat, 
+and can set the contents via echo.  For example:
+
+% cat /sys/bus/pci/drivers/ipw2200/debug_level
+
+Will report the current debug level of the driver's logging subsystem 
+(only available if CONFIG_IPW_DEBUG was configured when the driver was 
+built).
+
+You can set the debug level via:
+
+% echo $VALUE > /sys/bus/pci/drivers/ipw2200/debug_level
+
+Where $VALUE would be a number in the case of this sysfs entry.  The 
+input to sysfs files does not have to be a number.  For example, the 
+firmware loader used by hotplug utilizes sysfs entries for transferring 
+the firmware image from user space into the driver.
+
+The Intel(R) PRO/Wireless 2915ABG Driver for Linux exposes sysfs entries 
+at two levels -- driver level, which apply to all instances of the 
+driver (in the event that there are more than one device installed) and 
+device level, which applies only to the single specific instance.
+
+
+1.4.1 Driver Level Sysfs Helper Files
+-----------------------------------------------
+
+For the driver level files, look in /sys/bus/pci/drivers/ipw2200/
+
+  debug_level  
+	
+	This controls the same global as the 'debug' module parameter
+
+
+1.4.2 Device Level Sysfs Helper Files
+-----------------------------------------------
+
+For the device level files, look in
+	
+	/sys/bus/pci/drivers/ipw2200/{PCI-ID}/
+
+For example:
+	/sys/bus/pci/drivers/ipw2200/0000:02:01.0
+
+For the device level files, see /sys/bus/pci/[drivers/ipw2200:
+
+  rf_kill
+	read - 
+	0 = RF kill not enabled (radio on)
+	1 = SW based RF kill active (radio off)
+	2 = HW based RF kill active (radio off)
+	3 = Both HW and SW RF kill active (radio off)
+	write -
+	0 = If SW based RF kill active, turn the radio back on
+	1 = If radio is on, activate SW based RF kill
+
+	NOTE: If you enable the SW based RF kill and then toggle the HW
+  	based RF kill from ON -> OFF -> ON, the radio will NOT come back on
+	
+  ucode 
+	read-only access to the ucode version number
+
+
+2.   About the Version Numbers
+-----------------------------------------------
+
+Due to the nature of open source development projects, there are 
+frequently changes being incorporated that have not gone through 
+a complete validation process.  These changes are incorporated into 
+development snapshot releases.
+
+Releases are numbered with a three level scheme: 
+
+	major.minor.development
+
+Any version where the 'development' portion is 0 (for example
+1.0.0, 1.1.0, etc.) indicates a stable version that will be made 
+available for kernel inclusion.
+
+Any version where the 'development' portion is not a 0 (for
+example 1.0.1, 1.1.5, etc.) indicates a development version that is
+being made available for testing and cutting edge users.  The stability 
+and functionality of the development releases are not know.  We make
+efforts to try and keep all snapshots reasonably stable, but due to the
+frequency of their release, and the desire to get those releases 
+available as quickly as possible, unknown anomalies should be expected.
+
+The major version number will be incremented when significant changes
+are made to the driver.  Currently, there are no major changes planned.
+
+
+3.  Support

+
+How to use dm-crypt and swsusp together:
+========================================
+
+Some prerequisites:
+You know how dm-crypt works. If not, visit the following web page:
+http://www.saout.de/misc/dm-crypt/
+You have read Documentation/power/swsusp.txt and understand it.
+You did read Documentation/initrd.txt and know how an initrd works.
+You know how to create or how to modify an initrd.
+
+Now your system is properly set up, your disk is encrypted except for
+the swap device(s) and the boot partition which may contain a mini
+system for crypto setup and/or rescue purposes. You may even have
+an initrd that does your current crypto setup already.
+
+At this point you want to encrypt your swap, too. Still you want to
+be able to suspend using swsusp. This, however, means that you
+have to be able to either enter a passphrase or that you read
+the key(s) from an external device like a pcmcia flash disk
+or an usb stick prior to resume. So you need an initrd, that sets
+up dm-crypt and then asks swsusp to resume from the encrypted
+swap device.
+
+The most important thing is that you set up dm-crypt in such
+a way that the swap device you suspend to/resume from has
+always the same major/minor within the initrd as well as
+within your running system. The easiest way to achieve this is
+to always set up this swap device first with dmsetup, so that
+it will always look like the following:
+
+brw-------  1 root root 254, 0 Jul 28 13:37 /dev/mapper/swap0
+
+Now set up your kernel to use /dev/mapper/swap0 as the default
+resume partition, so your kernel .config contains:
+
+CONFIG_PM_STD_PARTITION="/dev/mapper/swap0"
+
+Prepare your boot loader to use the initrd you will create or
+modify. For lilo the simplest setup looks like the following
+lines:
+
+image=/boot/vmlinuz
+initrd=/boot/initrd.gz
+label=linux
+append="root=/dev/ram0 init=/linuxrc rw"
+
+Finally you need to create or modify your initrd. Lets assume
+you create an initrd that reads the required dm-crypt setup
+from a pcmcia flash disk card. The card is formatted with an ext2
+fs which resides on /dev/hde1 when the card is inserted. The
+card contains at least the encrypted swap setup in a file
+named "swapkey". /etc/fstab of your initrd contains something
+like the following:
+
+/dev/hda1   /mnt    ext3      ro                            0 0
+none        /proc   proc      defaults,noatime,nodiratime   0 0
+none        /sys    sysfs     defaults,noatime,nodiratime   0 0
+
+/dev/hda1 contains an unencrypted mini system that sets up all
+of your crypto devices, again by reading the setup from the
+pcmcia flash disk. What follows now is a /linuxrc for your
+initrd that allows you to resume from encrypted swap and that
+continues boot with your mini system on /dev/hda1 if resume
+does not happen:
+
+#!/bin/sh
+PATH=/sbin:/bin:/usr/sbin:/usr/bin
+mount /proc
+mount /sys
+mapped=0
+noresume=`grep -c noresume /proc/cmdline`
+if [ "$*" != "" ]
+then
+  noresume=1
+fi
+dmesg -n 1
+/sbin/cardmgr -q
+for i in 1 2 3 4 5 6 7 8 9 0
+do
+  if [ -f /proc/ide/hde/media ]
+  then
+    usleep 500000
+    mount -t ext2 -o ro /dev/hde1 /mnt
+    if [ -f /mnt/swapkey ]
+    then
+      dmsetup create swap0 /mnt/swapkey > /dev/null 2>&1 && mapped=1
+    fi
+    umount /mnt
+    break
+  fi
+  usleep 500000
+done
+killproc /sbin/cardmgr
+dmesg -n 6
+if [ $mapped = 1 ]
+then
+  if [ $noresume != 0 ]
+  then
+    mkswap /dev/mapper/swap0 > /dev/null 2>&1
+  fi
+  echo 254:0 > /sys/power/resume
+  dmsetup remove swap0
+fi
+umount /sys
+mount /mnt
+umount /proc
+cd /mnt
+pivot_root . mnt
+mount /proc
+umount -l /mnt
+umount /proc
+exec chroot . /sbin/init $* < dev/console > dev/console 2>&1
+
+Please don't mind the weird loop above, busybox's msh doesn't know
+the let statement. Now, what is happening in the script?
+First we have to decide if we want to try to resume, or not.
+We will not resume if booting with "noresume" or any parameters
+for init like "single" or "emergency" as boot parameters.
+
+Then we need to set up dmcrypt with the setup data from the
+pcmcia flash disk. If this succeeds we need to reset the swap
+device if we don't want to resume. The line "echo 254:0 > /sys/power/resume"
+then attempts to resume from the first device mapper device.
+Note that it is important to set the device in /sys/power/resume,
+regardless if resuming or not, otherwise later suspend will fail.
+If resume starts, script execution terminates here.
+
+Otherwise we just remove the encrypted swap device and leave it to the
+mini system on /dev/hda1 to set the whole crypto up (it is up to
+you to modify this to your taste).
+
+What then follows is the well known process to change the root
+file system and continue booting from there. I prefer to unmount
+the initrd prior to continue booting but it is up to you to modify
+this.

@@ -311,3 +311,10 @@ As a rule of thumb use encrypted swap to protect your data while your
 system is shut down or suspended. Additionally use the encrypted
 suspend image to prevent sensitive data from being stolen after
 resume.
+
+Q: Why we cannot suspend to a swap file?
+
+A: Because accessing swap file needs the filesystem mounted, and
+filesystem might do something wrong (like replaying the journal)
+during mount. [Probably could be solved by modifying every filesystem
+to support some kind of "really read-only!" option. Patches welcome.]
