As said on IRC I've started bisecting this, but ran into some problems:
1. v2.6.32 from Linus' tree (vanilla) oopses on boot (and I cannot see the whole kernel panic message); tried Ubuntu config and from "make localyesconfig"
2. I've tried 2.6.31-22-generic from the Ubuntu repos (Karmic), which also failed (although I've thought that this has regressed in Lucid). Same with 2.6.31-14-generic.

Looking at the output of "lshw", I see:
  capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram

Shouldn't "dvd-rw" show up there?

However, I am not sure to have ever burnt a DVD+RW on the device. I think I will stick to using a DVD-R for the moment, and try other RWs later.
