How do I get a microsecond clock on the RISC 6000?

[Lon Fisher]

	Many IBM employees and salespeople inform me that a
microsecond granularity clock is available on the 6000.  However,
it requires some kernel modification.  Does anyone know where to
start on this project?  So far, I've had lots of talk and little
action.  I am primarily interested in such a clock for accurate
timing of events less than 10ms apart.

you for your assistance.
