[Nouveau] Bug or not?

[Pierre Moreau]

Does the Nvidia card auto-suspends or do you have to force it? If not, does it report some “failed to parse _DSM” message?
I have a mid 2009 MBP who uses a different _DSM handles than the ones Nouveau currently supports, and I wondered if they were related to the Apple Gmux or not. So, as you have a different model with a different Nvidia card but still with an Apple Gmux, I’d be interested to know if you have the same _DSM handles as I have.
