It turns out I've had this in my tree since July 6 (from Jindrich
Makovicka), sent to Len on July 9. Maybe he's merged it somewhere already.

I have seven acpi patches here, some of which have been in -mm for a very
long time. I'll resend them all. Could someone please promptly ack them for
2.6.13 or merge them somewhere or nack the things?

Thanks.
