Two main answers:

1) Use psradm and the related commands (psrinfo, pset_<various>, can be
found via the psradm man page) to reconfigure the processor set and/or turn
one processor off. (Note: The man page explicitly states that this
shouldn't be done for benchmarking, but it doesn't go into detail regarding
what the pitfalls are; I suspect that this amounts to turning off the
processor, but not removing its overhead from the OS)

2) Do "disable cpu <number>" at the console prompt. I suspect this is what
I'm really after.

Thanks as always
