This is sort of hard to debug since I cannot reproduce it at will - sometimes it happens several times in a row, other times it doesn't happen for days or even weeks. It doesn't seem to be a hardware defect, though, since I have a second X31 which shows the exact same symptoms. Also, while I don't remember exactly when it started, I know it used to work just fine (probably back on etch, but the laptop was running Ubuntu at that time).
Can you try a more recent ati/radeon driver package?
Some are available at http://people.debian.org/~bgoglin/rebuilds/Xserver1.4/
