I'm not sure that it is a 32-bit vs. 64-bit thing as much as it is an
evolution of Performance Monitor from individual Book IVs into the
ISA.  Saying differently, the SPR number for MMCR0 is now specified
in the ISA and is the same for 32 and 64 bit implementations
... and is also the same for embedded versus server implementations.
When the 604 came out, the performance monitor was not yet part of
the ISA.

Other than that ...
