I don't want to unnecessarily expand your scope, but while you're  
doing this, it might make sense to keep in mind the new Larrabee  
instructions as well. They operate on 512-bit registers, and there's a  
(slightly indirect) reference available here:

I'm not suggesting adding these now, just that they might be  
interesting to keep in mind while you're doing this work.
