ok, thanks for instructions: will do and let you know as soon as I'll be 
able to reproduce it (again, with xorg-dev it happens more seldom, 
sporadically and I've no exact STR for it)

No, I don't use VB at all.
In the vast majority of cases I've observed so far crashes took place 
while was working in browser (cwww/chromium). One more thing (well... I 
know it sounds a bit odd... but still): it never crashed during surfing 
heavy pages or audio/video playback but on submitting simple text 
messages (issue tracking system, code review tool, wiki and so forth).
