SubjectRe: Linux 2.6.23-rc4: BAD regression

Len? Should we just revert it?

That commit has been very painful. First it lost all registration of the
query methods, and now this.

Daniel - can we please have a before/after dmesg on your machine,
preferably with ACPI debugging enabled? And for ACPI stuff, it usually
does help to fill in a bugzilla entry, since the ACPI people actually do
track things there...
