Given that the screenshot shows that the line just before the crash 
is "radeonfb (0001:02:00.0): ATI Radeon [d" which looks truncated the 
most likely candidate looks to be drivers/video/aty/radeon_base.c (in 
__devinit radeon_map_ROM).
That function even has some suspicious looking comments immediately above 
the call.

Finding out for sure would probably require building a custom installer 
using a kernel with some added debugging statements. Is that needed?
