I'd like that todo too, but notably most 3D extensions are 32bit floats and
only a few instructions deal with 2/4/8 (int/shorts/bytes) values in mmx
registers. For further processor differentiations there should be probably code
to recognize K6/2+ K6/3+ Duron Athlon. They share the same 3D extended
instruction set.
