Please try booting with "pci=routeirq"
If that doesn't work, please take stock 2.6.8.1 and apply the latest
patch here:
http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/patches/release/2.6.8/
and give it a go.

This will bring your kernel up to the same ACPI patch that is in the -mm
tree, but without all the other stuff in the mm tree.

If it fails, then ACPI broke.  If it works, then something in -mm broke
ACPI.

thanks,
