The issue is that we don't support the _OSI method yet, otherwise we could
advertise FreeBSD as being both Windows 2k and XP compatible.  Your best
workaround is to just unconditionally store 0x02 into \WNTF at the end of
the \_SB._INI function.  Since the custom AML will only be loaded by
FreeBSD, you won't affect other OS's with this change.

Bob, any word on _OSI implementation?
