Hi Alex,

I still would like to be able to disable DVI and just use VGA while the
DVI cable is still plugged in. I saw your "superpatch" in bugzilla and
thought I should try it out because you wrote that you have fixed various
issues with the driver.
I compiled X from CVS but somehow couldn't get it going. I reinstalled
modular xorg afterwards and just copied over the * files.
It didn't fix my issues, though :( Well, at least I tried.
