Yes, the system hangs as soon as gdm starts X. Hard Locks regardless of 
what options I use or do not use.

I can't get a backtrace with ssh because X isn't running when I ssh in. 
Sometimes the computer itself is completely unresponsive and I can't ssh 
at all.

On very rare occaissions, I can get it started with dri enabled, but X 
will eventually hang anyway.

I'm attaching a gdb that I collected using the single machine method 
from the affected machine.

By the way I go by "ZitZ" in the #radeon irc.
