I think there actually is a way to install Windows 2000 but it involves replacing one of the files on the disc with a file on the XP disc. Then once installed, you would still need to find your own drivers.
Intel's graphics drivers still support Windows 2000, so that's not a problem. Even though this is a MacBook forum, I'll still point out that it might be a little bit more troublesome to get AMD or NVIDIA drivers for newer cards to work on Windows 2000.
