So I'm the first one? ;)

Your patch (http://www.ussg.iu.edu/hypermail/linux/kernel/0309.3/0341.html)
FIXES things for me :-)

This time I've tried 2.6.0test6 + all acpi patches from 2.6.0-mm1 (ls *acpi*
in akpm broken-out directory) + your patch and things work fine :)
Note that 2.6.0+all acpi patches from 2.6.0-mm1 without your patch doesn't
work.
