aibs* at acpi? broken in -current

["Scott Ellis" <scotte%warped.com@localhost>]

Upgraded my ASUS P5W DH system from amd64-current of May 3rd to -current
of today, and see that aibs* at acpi? doesn't attach any longer.  Dmesg
shows:

aibs0 at acpi0 (ASOC, ATK0110-16843024): ASUSTeK AI Booster
aibs0: failed to evaluate GGRP: AE_TYPE
aibs0: no sensors found

I didn't rev the BIOS during the upgrade, so I'm figuring it's an ACPI
interpreter regression issue.

Should I send-pr, or does somebody have a clue and something for me to
try? :-)
