Nope, Windows 2000 is like NT 5.0, XP is like NT 5.1. :( One possibility is to fix it in SeaBIOS instead: if you get a 2.0 FADT and an XSDT and no RSDT, it can build an RSDT and a 1.0 FADT itself, patching the RSDT to point to it. It's a hack, but it's the only place I see to make it "just work". And it could be extended nicely in the future. All QEMU would have to do is to provide an XSDT _instead_ of an RSDT.
