===================

History: X11 server was stable on karmic and in the first weeks of
lucid. It happened yesterday and today. Probably due to reboot after a
new kernel. X11 was unusable with this graphic chip in jaunty. It was
really stable in intrepid and before. Since karmic, there are refresh
errors: textlines become garbage; sometimes they disappear completely -
you'll recognize, as soon as you don't understand context of the text
you read anymore ;)
