Sort of, one needs either fhc(4) or sbus(4) (or powermac(4) on
powerpc) so the front-end is built. Not sure if it is a good idea
to change sys/conf/files to build zs.c only when the respective
front-end is also built, if a machine doesn't have a bus zs(4)
can hang off from it doesn't make much sense to add zs(4) to
its kernel config file in the first place. The current behaviour
at least serves as a hint that zs(4) can be removed from the
kernel config file...
