I've made a kernel with the latest fix available in this PPA:
https://launchpad.net/~brian-rogers/+archive/graphics-fixes-testing

If it gets good feedback, I'll copy it to my regular graphics-fixes PPA.

This kernel is based on Natty's 2.6.37 kernel, has the changes in drm-intel-next applied, and the patch at https://bugs.freedesktop.org/show_bug.cgi?id=27187#c291 is added. I've produced builds for Lucid, Maverick, and Natty. It has a cache coherency checker, so you'll see periodic messages in dmesg reporting on the number of flushes and whether any problems are detected.
