I can confirm this bug: upgrading to xserver-xorg-core 1.0.2-0ubuntu10.3 and rebooting the system fails to start the xserver (no screens found). I tried to reinstall my drivers, but this fails. I didn't touch the xorg.conf. This seems a very severe bug to me...
System: Matrox P650 (dualhead) with the unofficial Matrox drivers that can be found on http://www.tux-home.at
