VIS is not well designed enough, unfortunately.  It's the most
primitive of all the multimedia instruction sets.  For example,
implementing an IEEE compliant IDCT in VIS is like pulling one's
toenails out whereas on altivec and MMX it's mostly sane.

Yes, I do see the value in using the vector stuff.
