Maybe we could have a list of legacy (ISA?) devices for drivers like vgacon to 
attach to?  The bus info could be stuffed into the legacy device structure

How do you mean?  Legacy I/O port accesses just become strongly ordered memory 
transactions, afaik, and legacy memory accesses are dealt with the same way.
