MMX Instructions

They're just instructions. In fact, if one were to forego portability, MMX
and other SIMD instructions can probably be used to very good effect 
since the microkernel and the servers likely doesn't do any floating point
operations (MMX and FP share registers, so it's not easy to just
mix and match).
