In article <Pine.NEB.4.33.0306181019520.18912-100000@vespasia.home-net.icnt.net> you write:

It's there because upc is a driver for a chip (a random ISA super-IO chip),
and hence appears in dev/ic.  At some point, I'll re-work the acorn26
support to use isa(4) and the new direct-config support in there, and then
upc(4) will be able to vanish.
