Subject: [drm] nouveau iMac crashes and burns

I had figured this would happen,
but was curious to see if this
new bad boy would work.
(probably why fedora 12 doesnt boot as well).

basically the system freezes during boot once
drn nouveau is loaded. here's dmesg captured
with firescope:(a bit long)
