The Gflop specs for the G4 apply only to the Altivec instructions,
which were not used! It is only a subset of floating point(FP)
operations that this will help. It won't help integer, it won't help
the hard drive, etc. If you want to do a lot of FP ops on arrays, it
should be a winner when enabled.
