Thanks, I will have a look into it; reasonably soon I hope -- I'm
updating my tree right now. I am quite surprised you care about this
platform too.

This is not true for all systems -- the clock rate is based on the
TURBOchannel clock and it varies across systems. And some have no counter
in the I/O ASIC at all (it has been added in a later revision of the
chip), which the old code handled albeit not in the prettiest way (by
chance actually, as originally I did know of the older revision).
