The question should be, "is it still true that AltiVec does not support 
double-precision floating point?"

It apparently still does, so AltiVec gives no (significant) benefit for 
POV-Ray. Color computations might be faster (because POV-Ray uses 
single-precision floating point for those) provided the used compiler 
can optimize for AltiVec.
