I'm unable to test the latest development release of Ubuntu, as I can't find it as a live CD and can't afford to upgrade my system to an unstable release. If there is a live CD and someone could point me to it, I'd be more than happy to try it.
I've tested the latest mainstream kernel linux-image-2.6.38-999-generic (2.6.38-999.201101261132) - it doesn't fix the problem. What works however is the "model"-option for snd-hda-intel that Michael Helmling posted in comment #5. This works for linux-image-2.6.35-24-generic, linux-image-2.6.35-25-generic and the above mentioned linux-image-2.6.38-999-generic.
As requested, I've removed the tag "needs-upstream-testing" and added the apport information (when running linux-image-2.6.35-25-generic without the fix from #5).
