+Why:	There are some drivers still using V4L1 API, despite all efforts we've done
+	to migrate. Those drivers are for obsolete hardware that the old maintainer
+	didn't care (or not have the hardware anymore), and that no other developer
+	could find any hardware to buy. They probably have no practical usage today,
+	and people with such old hardware could probably keep using an older version
+	of the kernel. Those drivers will be moved to staging on 2.6.37 and, if nobody
+	care enough to port and test them with V4L2 API, they'll be removed on 2.6.38.

-Why:	The vtx device nodes have been superseded by vbi device nodes
-	for many years. No applications exist that use the vtx support.
-	Of the two i2c drivers that actually support this API the saa5249
-	has been impossible to use for a year now and no known hardware
-	that supports this device exists. The saa5246a is theoretically
-	supported by the old mxb boards, but it never actually worked.
-
-	In summary: there is no hardware that can use this API and there
-	are no applications actually implementing this API.
-
-	The vtx support still reserves minors 192-223 and we would really
-	like to reuse those for upcoming new functionality. In the unlikely
-	event that new hardware appears that wants to use the functionality
-	provided by the vtx API, then that functionality should be build
