Please contact me if I can help in any way (I'm subscribed > to lkml, but not to other X or kernel related lists). Can you please boot with drm.debug=0xf on both good and bad kernels and then grab dmesg from each? To make sure we don't forget this please file the above summary plus dmesg files as a new bug against dri -> drm(intel) on bugs.freedesktop.org. Please add "[ilk bisected]" to the bug summary so it shows up in all the right searches for us.
