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).
