After upgrading my Nvidia Optimus powered laptop to 3.5.0-27 I experienced this bug, so I switched back to 3.5.0-26. But yesterday I wasn't watching the GRUB menu and accidentally booted to 3.5.0-27, and all of a sudden it worked again. No idea what changed, I did install some other updates in between, but no kernel updates. I haven't tried 3.5.0-28 yet.
