A kernel regression is less likely I think, you'd see problems all over the shop I'd bet. Same problem on 2.6.31 as well as 2.6.30.

Do you have the same graphics card as us? (try 'sudo lshw -class display')? Also, posting ~/.xsession-errors and /var/log/Xorg.0.log will be useful to the developers :)
