strange engine noises from inexpensive autos:-)

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)
Also, please send me the output from acpidump.
thanks,
-Len
ps
If you don't have acpidump, you can get it from pmtools here:
