If you boot using acpi=off you can use the Linux Firmware Developers
Kit ( http://linuxfirmwarekit.org/ ) to debug ACPI issues.  Then
you'll have lspci available to check against what the tables are

I couldn't use the factory DSDT for my mainboard because so many of
the initialization values were different when booted with Coreboot.

Linux is much more forgiving.  I personally wouldn't try Windows
without Linux working.  There's much more debugging information
available with Linux.

I haven't looked at it since then.  One of the things that makes my
s2895 challenging is multiple PCI root buses.  I haven't gotten that
quite right yet.
