Hi!

Problem with powering off the nvidia card on ASUS N61 is solved, nouveau
kernel module caused the crash when powering off while loaded.
Going through my DSDT, PEGR.GFX0._PS0 and _PS3 seems also to be of
interest in terms of switching graphics, since they call _ON and _OFF. I
just didn't find the time for testing them yet.

Cheers

Alex
