Robin, thanks for filing the upstream bug report. It would be nice if you could also test with a Karmic LiveCD (on a USB stick if you would like) and report the result and Xorg.0.log with ModeDebug enabled upstream. Karmic has a very recent development version of the driver (from June 2nd) and I think the upstream developers would appreciate a confirmation with a recent driver. Alternatively you may use Jaunty with the xorg-edgers repository, but I think that is more of a hazzle.
