I'm running gentoo, which handles the module compilations for me,
and I've not yet learned git.  Since you think you've fixed the bug,
and your suggestion of using xrandr --output VGA --mode gets my screen
working correctly again, I'm reluctant to invest the time necessary to
figure out how to do a git checkout, build the module, and get it loaded.
However, if it would help out the project for me to do that to confirm
that your fix fixes my particular bug, I'll find the time to do it.

Either way, thanks very much for your help!
