The nva3 copy engine exhibits random memory corruption in at least one case, the GeForce 320M (nv50, 0xaf) in the MacBookAir3,1. This patch omits creating the engine for the specific chipset, falling back to M2MF, which kills the symptoms.
I've pushed this (with slightly modified commit message) to nouveau git.
I'll get it to Linus' tree in a future -fixes merge.
Thanks, Ben.

Hi Ben,
this patch is still needed in 3.6-rc1, so perhaps we should apply it after all. I have been running it without problems for a long time now.
Thanks, Henrik
