This should be fixed with the above mentioned patch. The issue is that the bios fumbles around with the output configuration behind our backs, so the new paranoid modeset code in 3.7+ freaks out about the state mismatch between sw and hw.
The patch above should detect this situation and undo any bios-induced damage.
Even with the patch, I still am seeing the issue (in 3.8).
Thanks, Richard
