Presumably the (lack of) MMX since it already has VESA 2. Of course, since they already emulate FPU, it can't be too hard to extend to MMX. IIRC, there is a Linux MMX emulator's sources they could glean from. (Unlikely they will do this, of course, at least not soon, but who knows.) Their excuse will probably be something like, "Not enough games use it" or such.

Beware hardcoded version checks. I'm not saying you're wrong in this instance, but there's no easy way to override this (that I know of, does SETVER change this on WinXP??) in case whatever assumption is faulty (or would work with specific video drivers).

I'd rather you did strcmp(getenv("OS"),"Windows_NT") or similar. At least then the user could set / unset it manually if needed. Kludgy but better than nothing.
