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.
