Yeah, reset button works fine... When I say it doesn't work, I mean the 
machine itself resets & reboots. But the graphics adapter doesn't recover at 
all. I still have no screen output.

The ssh into the machine is after running startx to bringup the XServer. 
All-in-all it syas to me something is fiddling the card (Saphire Radeo 9600 - 
256MB) into some state that it just can't recover from without a power-cycle. 
Not bad enough to screw the PCI bus of course, so everything keeps going, but 
there's no indication in the log to say there's actually anything that fails 
to the r300 code...
