[drm] nouveau iMac crashes and burns

[Justin Mattock]

o.k. I didn't see the urls at the bottom pointing
to where to get the firmware(was figuring out the trace thing.

Anyways I think I need to generate a new firmware file because
even with the firmware compiled in I still freeze up:

looking at
http://nouveau.freedesktop.org/wiki/CtxInit
seems understandable to me, and I'm willing to
try this out(even if I go crazy), but could take a while.
