I suspect the BIOS is configuring the hardware differently now. We can fix the driver to do the same thing if we know what the differences are. If you add

Option "ModeDebug" "yes"

to the Device section of your xorg.conf file, it will dump lots of register information to the log file. Comparing broken vs non-broken machines may uncover something that we've neglected to configure in the driver.
