[Julien-Charles Lévesque <levesque.jc@xxxxxxxxx>]

I tested this on my laptop (u30jc, Ubuntu 11.04) and I confirm that this
fixed some issues (for one, vgaswitcheroo now shows in /sys/kernel/debug).

Was able to turn discrete card on and off, but echoing DDIS to switch caused
my screen to blank when I logged out. Screen gone.
