I like the idea (actually, quite the direction I'd like to go), but
unfortunately it's more compilicated than that.

Some drivers don't use these fields, eg. 8250 determines the mapsize
based on several factors, at the time of the mapping is done. That's
one of the things my patches shall clean up.
