That looks fine to me as well. However, the best solution is something which
Luca suggested a few months ago, which is to use the functions defined in
altivec.h. These are C functions which map directly to Altivec machine
instructions. I am willing to help out, but I don't find the current lpc_asm.s
very easy to follow, and my time is quite limited (my last patch to a free
software project took almost three months to get into decent shape!).
It would help to hear from Chris, I think.

Mine is the same as Luca's.
