On my system:

FreeBSD RabbitsDen.RabbitsLawn.verizon.net 8.1-STABLE FreeBSD 8.1-STABLE
#0 r215086: Wed Nov 10 11:07:30 EST 2010
root at RabbitsDen.RabbitsLawn.verizon.net:/usr/obj/usr/src/sys/TPX60  i386

running on ThinkPad X60, I get proliferation of 

"acpi_tz0: error fetching current temperature -- AE_NOT_FOUND"

messages after applying the patch.

Verbose dmesg from "before" and "after" cold boots are available at:

http://members.verizon.net/~akovalenko/ACPI/dmesg.before.bz2
http://members.verizon.net/~akovalenko/ACPI/dmesg.after.bz2

respectively.

Now, on this machine tz0 is not a real thermal zone but some kind of
implement to initiate system shutdown for some case I never had enough
time or inclination to track through ASL. Real thermal zone is tz1.

If I can provide any additional information or test any patches, please,
let me know.

Also, I would like to take this opportunity to thank you for your work.
