OK, three files attached; drm.good is from 2.6.35, drm.bad is from
2.6.36-rc2. I also stripped the times and did a diff, in case that's
useful.

If you'd like output from right around the bad commit, say the word;
that will take a bit of building time (I didn't keep all those bisect
kernels around) but I can do it.

Thanks,

jon
