interrupts to devices would not work.
but i can check if this is a NOP with your acpidump output.

Thanks for the dmidecode output.
Do you notice any functional difference when booting with
"acpi_osi=Linux" (default for 2.6.22 and earlier)
vs.
"acpi_osi=!Linux" (default for 2.6.23 and later)
Please send me the output from acpidump.
I've got this box in the blacklist already b/c
similar machines showed that OSI(Linux) on them is a NOP.
thanks,

ps
If you don't have acpidump, you can get it from pmtools here:
