Do not confirm your own bugs, please.  We like to use peer review.
It also happens on powerpc-apple-darwin6.6 so it looks like a generic bug:
_prefetch:
        dcbtst 0,r3
        blr

gcc -S -O -Wall -o - pr11599.c -v -maltivec, where pr11599.c contains:
void t(void *p, int s)
{
  if (s)
    __builtin_altivec_dst (p, 0, 0);
}
produces:
_t:
        li r0,0
        dst r3,r0,0
        blr
So very much a generic bug.
