I tried acpi table overriding, but it did not work for me.
In your tree there seem to miss acpi initrd overriding doku:
Documentation/acpi/initrd_table_override.txt
?
And your tree is 3.6.0-rc6-default+ based, right?

I tried it like that:
mkdir -p kernel/firmware/acpi
cp dsdt.aml kernel/firmware/acpi
find kernel | cpio -H newc --create > /boot/instrumented_initrd
cat /boot/initrd >>/boot/instrumented_initrd

modified /boot/grub/menu.lst and pointed to /boot/instrumented_initrd

-> no override messages in dmesg, no overriding happened at all.

Did I oversee something?
