[PATCH] intelfb: fix accel detection when changing video modes

Changed the tests in intelfb_set_par to check also the parameter
var.accel_flags.  If null, do nothing about ring buffers.

Now, the DirectFB i830 driver could nicely work even if intelfb is hw
accelerated.  Just change the /etc/fb.modes file to disable console hw
acceleration when starting a DirectFB app.
