Comment 540 for bug 359392

Very similar bugs were present even in Hardy, such as https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/233896. I remember someone uploading X & intel packages from the never released DRI2 stuff (or sth like that) to the bug, which worked, but I don't know if they were the versions that made it into Intrepid. The thing is, to be completely on the safe side, maybe the driver for Gutsy should be considered. Which is kind of unthinkable...
