FPC doesn't use/generate any altivec/vmx code at this time/

Power and PowerPC have been sort of merged quite a while ago already
and use the same instruction set now (at least from a non-OS
developer point-of-view). But it's indeed quite probable that the
cache line size on a Power5 is larger than 32 bytes (the G5 was
derived from the Power4).
