My understanding is that the windows acpi code is actually very similar to or derived from the intel code.
As for bug for bug compat, that's really more an issue of broken bios. I.e., the acpi byte code is broken, not the implementation that interprets the byte code. Windows doesn't necessarily do anything crazy, it's the bios that asks "is this windows?" And then shits itself if the answer is no.
