The license you have to agree to to download it permits implementation
for firmware, but not for the OS: 1(a)(iii), 1(b), 2(b)(b), 3.

According to the documentation at the end of the page of the URL
you posted above, the OS has to be full PnP compliant for it to
work as expected, and multiboot is not supported.

For thise interested in pursuing this, more information (no license
agreement required) is available from:

http://www.microsoft.com/hwdev/platform/performance/fastboot/fastboot-winxp.asp

Though I expect you won't be able to implement without the specification.

I guess looking at the Linux code as a reference is OK... they
violated the license, not you, so it's not the same thing as you
violating the license.
