I think this is related to ACPI changes to how _PSS objects are handled.
Reassigning for now.
Did you boot with acpi=off?
Full dmesg would be helpful. Better try more recent kernel (best 2.6.16-rc2 or
higher, a lot ACPI changes came in there).

this problem is still happening... :-( i'm so desperate for a fix that i've even
tried to do my own analysis, but am stuck.. someone, please help? :-)
Can you try recent kernels and make sure if the problem still exists?
Please reopen this bug if it's still present with kernel 2.6.20.
