I just tried to build & run this on freebsd.

Have you tried turning the original interrupt code back on?  See Line 422 in 
radeon_context.c.  I got an immediate failure when running gears on freebsd -- 
same behaviour, looks like it isn't getting an irq back after requesting one.

The difference is now you don't have to run quake first, so it looks like 
there's been a regression.
