If it isn't reproduceable by other people on Radeon 7500, then it 
most likely is bad video memory, in which case you would replace 
the video card with a new one.

If it is an actual software bug, then it should be reproduceable
on all Radeon 7500 hardware, and likely all Radeon hardware
period, since the code is shared with all Radeon hardware.  If 
this is the case, I'll most likely start getting bug reports by 
the dozen.

You can swap the card with another 7500 and see if the problem 
goes away.  Also get others with Radeon hardware to try and 
reproduce.  If all else fails, then use the supported XFree86 
that shipped with shrike - 4.3.0-2.  If the problem goes away, 
then it could be a new driver bug perhaps.
