Kernel 2.6.32 helped the situation, definitely. But unfortunately I ran
into som other compatibility problems with both PPA mainline-versions
and custom-compiled versions from upstream (missing App-armor, somewhat
strange/altered fs-mounting-behaviour at boot, readahead not working,
extremely slow hibernation). In the end I decided to stick to the
2.6.31-based kernels distributed with Ubuntu Karmic. I guess things will
get better when Lucid comes around..
