Thanks for testing.

I've inspected the generated DSDT and SSDT files, and I don't see
anything wrong with them.  (To inspect a generated SSDT, uncomment the
call to hexdump(), cut and paste the hexdump output into SeaBIOS'
tools/transdump.py, and then call "iasl -d" on the output.)

It seems the Windows acpi interpreter is significantly different from
the Linux one.  The only guess I have is that Windows doesn't like one
of the ASL constructs even though they all look valid.  I'd try to
debug this by commenting out parts of the ASL until I narrowed down
the parts causing the problem.  Unfortunately, I don't have Windows
2008 to do this directly.

Any other ideas?
