Hello Guillaume,

Since you've done a bunch of work on Altivec optimizations, and the
instruction set of a CBE is not that different from Altivec, perhaps you
should take this one on?  I for one am curious to see what the practical
performance on a CBE is; I've done some (simulated) tests but there's
nothing like seeing it actually work.

P.S. People without the right hardware can still hack on this if
interested: have a look at
