The way the cputable patch is now, the rev 4 would match the base revision
anyway. Maybe it makes more sense to make PVR xxxx01xx and xxxx02xx
explicitly match the old power5+, and make everything else match power5++?
I guess it all depends on the chance of IBM doing another major rev of
power5. Given it's current phase of product maturity I suppose it's not
all that likely. Doing it this way saves yet another cputable entry as
well, since it would otherwise mean two added entries instead of one.
