The fix is now in Linus' kernel tree, and should be in today's snapshot here: http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/2010-04-28-lucid/ You can install this kernel in your Karmic system to try out (unless you have a Lucid system). The updated -ati driver for Karmic in https://launchpad.net/~xorg-edgers/+archive/drivers-only has been uploaded, but wait for the -tormod3 version to be built. The mesa packages from https://launchpad.net/~xorg-edgers/+archive/radeon are for lucid and I don't know if they can be installed in a Karmic system. so try first without. But to fix the corruption in all situations, all three packages must be updated.
