He was right --- this functionality is the kernel's responsibility.
Merging for easy reference.

Sounds like this is a regression.  Can you try the kernel from squeeze
or squeeze-proposed-updates, to confirm?

Please test without the nvidia and virtualbox drivers, so we can rule
those out as a cause (or track it down from that direction if one of
those turns out to be the cause).

Output of "dmesg" and of "acpidump" from immediately after booting
a working and a non-working kernel would be helpful, too.

Thanks and hope that helps,
