(Note that the firmware-linux-nonfree package is required for the radeon 
driver, not for fglrx, but the information you've provided shows that it 
was installed)

It seems like the crashes you're experiencing are more or less random 
and all over the place. I can think of two basic explanations for that: 
Either the GPU is scribbling over random system memory locations, or 
there is a problem with the RAM or some other hardware component in the 

You can test for the latter with the memtest86(+) or memtester package.
