It's been a while since I looked into the X logs on my spare machine (which has an ati card). Obviously my memories of what I used to do are now obsolete :-) There's also this new quirk called hal ... I recommend you post the current and previous logs as attachments, together with the output of eix for xorg-server and your drivers.
