The reason that vsbus was invented was to hold resources; merely
which part of the DMA area that is allocated for what and to 
lock the registers for simultaneous access. If this can be done
with the bus_* code, good! I don't know enough about this.
Otherwise there must be some way to keep the bus resources for 
both the VS3100 and VS4000. The VS4000 map reg implementation is
much more like the Unibus and can maybe be forced to share the
same resource keeping scheme.

The rest of the points would be just 'OK'.
