Hi Joanand,

I based my patches on the linux-3.18 branch of Nouveau's repo, which is more
up-to-date than 3.17-rc6: this explains the "if (nouveau_noaccel)" at least.

Great for the kernel panic! I noticed that using the patches, screen resumes
correctly when resuming the computer, rather than staying completely black.

Well, I'll work 9600M Gt acceleration, but I can't say if I'll succeed, nor
when. ;)

Best regards
