Paul MacKerras submitted patches for PPC32 last month, PPC32 chips have 
had VMX (AKA Altivec) for a while now. But the first PPC64 chips with VMX 
have just started shipping (in the Apple G5) so this is a new issue for 
PPC64. I've been waiting for the kernel headers (sigcontext) to settle.

BTW any man who thinks ppc sucks does not own a G5! ;)
