It's related to powernow somehow.  The powernow driver use ACPI in order
to get the needed configuration information.  Unfortunately, some BIOS
provide buggy _PSS packages.  It's likely harmless since other _PSS
packages are OK.  But to be sure, it would help if you provide a dump
of the acpi tables somewhere on the web, or, if you can't, send them
privately to me.  An acpidump -d -t will give us this information.

Note that the kernel log flood is already fixed under -current.
This will be MFC'ed soon to RELENG_6.
