Looks like the Embedded Controller could not be set up?
Then a lot ACPI things probably do not work.

Could document above in a bugzilla entry:
http://bugzilla.kernel.org

Best check for the latest BIOS, attach acpidump and dmesg of the latest 
mainline kernel (currently .27-rc3).

Also why you think the DSDT is broken and a diff how you fixed it would be 
great. Be aware that the latest BIOS might have modified/fixed DSDT code.
