Thanks for caring about this issue. I'm not sure if I have the very same hardware as Piotr, but I think I reproduced the problem with latest lenny kernel. See [0] As I have mentioned in a previous follow-up, the problem is solved removing virtuallization support, see previously posted patch 0.9-lenny.diff When this patch is applied, I get a working kernel. See [1] and mind that kernel panic at the end is caused by a totally different reason. If you think this is a different problem I may arrange further testing with some patches. I've also tried 2.6.30 from backports and it found working as is without needing any further patch.
