I don't think we have a regression in the newbus infrastructure,
because we never had this support there. The problem has always
been that we have treated the COM ports as a special case when
we shouldn't have. Granted, other bugs forced us to treat the
COM port specially (i.e. wiring the low-level console to a unit
number before bus enumeration proper), but this is just more of
the same...

My suggestion is to use uart(4) and not worry about the unit
number. Your console will work irrespective...
