There is a bus_space_mmap() and a bus_space_vaddr(), so if you can encapsulate everything within a bus_space_tag_t / bus_space_handle_t, you should be good.
Yes, it would be nice to have prop types for those sorts of things. I have been considering how to extend proplib at run-time with custom types (that would allow, for example, putting device_t's into a dictionary).
