I seem to be having this problem on a Lenovo X201 with i5-540, Lucid 64 bit.
I swapped over to Xorg from deb http://ppa.launchpad.net/xorg- edgers/ppa/ubuntu but that doesn't seem to be helping. As with the original bug report it seems to be frequent with high video activity. Last week I had it continuously while doing a mirrored video arrangement with projector - so much that the machine was unusable. Don't have access to the PJ at the moment but will post an update when I can get it again - if it's quickly and easily reproducible I guess it'll make it easier to find/fix the culprit.
