I still don't have a complete understanding of the issue, but I've
gone ahead and copied that change from geode into the dove driver.
That solves the problem, no more X server patching required.

I know X developers have no shortage of things to work on, but if
there is interest in diagnosing further, I'm available for further
debugging in order to complete our understanding.

Thanks,
