Xorg.0.log with ModeDebug, BusType PCI and DRI off  

Reported in Ubuntu Hardy using -ati driver from git 2008-04-04 and xorg-server
2:1.4.1~git20080131-1ubuntu6, https://bugs.launchpad.net/bugs/214105

At start-up an initial mode of 1440x900 is selected, which makes the monitor go
black. ddcprobe does not list this resolution, but it appears in the "probed

ATI Radeon 9250 5960 (AGP). (DRI was turned off in the attached log, since the
AGP  speed mismatch would freeze the computer.)
