I've done some further testing, and have two more observations to report:
1. Using the aforementioned 2.6.31 kernel with stock Ubuntu X11 packages works beautifully---no PPA packages are needed. (In fact, with the xorg-edgers packages, I was getting weird core/XI-event-translation errors that prevented the mouse from working in at least two GL apps.)
2. This bug is still reproducible in the Maverick Alpha 2 live CD environment.
