Alex,

Do you think this option is worth perusing?

I'm in no way a kernel/X/driver developer; but I'm familiar with most
linux admin tasks, building software from source and tracking down
problems, and I'm willing to give it a try if you think there's a
reasonable chance of this providing information that will help track
down my issue.

So this requires 2.6.30, and Jerome's drm tree?  (Can you point me to
where this is?  Assuming this is a "git" tree, the command use to pull
it would be quite helpful, since I'm more familiar with svn/bzr than
git.)  Anything else required/recommended?
