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.
