It will be, but it's quite broken now, I'm sorry. Haven't had time to
really work on it, and it's just been upsetting me that every 4
instructions implemented, I have to dig through the code to find what
broke.

Check just about any of that over again from the AltiVec branch, it's
been covered, because it had to be.  If you do your math correctly:
128 bits * 1 byte / 8 bits = 16 bytes   An AltiVec operational unit is
thus 16-bytes big.
