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)

in particular, please test the sound and wifi

Also, please send me the output from acpidump.

thanks,
-Len

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