you'd need something equivalent to the fpu emulator to run it ;(
basically mmx would run slower on non mmx machines and hence won't be much
use for a few years to come until enough of the market has them.
the speed increase isn't so great from what i've seen though, there are problems
with caching writes or something as i recall.
