Comment # 4 on bug 91523 from Ilia Bozhinov

I tested a kernel build with the relevant code commented(right after the
comment I posted) and indeed the kernel module works! (it loads and DRI_PRIME=1
allows me to run glxgears/glxinfo). What is more, now I get better power
savings because when driver is loaded vgaswitcheroo can turn off the nvidia
card.
