-What:	Support for lcd_switch and display_get in asus-laptop driver
-When:	March 2010
-Why:	These two features use non-standard interfaces. There are the
-	only features that really need multiple path to guess what's
-	the right method name on a specific laptop.
-
-	Removing them will allow to remove a lot of code an significantly
-	clean the drivers.
-
-	This will affect the backlight code which won't be able to know
-	if the backlight is on or off. The platform display file will also be
-	write only (like the one in eeepc-laptop).
-
-	This should'nt affect a lot of user because they usually know
-	when their display is on or off.
