You're making life far too hard for yourself. FreeBSD doesn't reward
you for trying to kludge things; the infrastructure you're looking for
wants you to be using our bus interfaces.
Have a look at pmap_mapdev() for what you're trying to do.

You're picking bad examples to work with, since both those drivers
support multiple operating systems. Try a much cleaner driver like,
eg. if_tl.
