That doesn't help, thanks for the hint.

You're right. Loading thermal.ko leads to the same message, yet the suspend to
ram works.

Yes, great, it works in 2.6.29-rc3!!! It's amazing, because, when I check acpi
in [1], I see no change which could have led to the fix.
I provided acpidump in [2] as information.

Well, I' consider the topic solved. I'll make further tests this weekend to test
all of my laptop functions, but my hopes are quite high.

Thanks a lot, the three of you.
