What rbus tries to do should be fixed properly. There should be a way
to allocate a bus region, and then do sub allocations from that
region. The obvious (to me) way to do it would be to create a function
that allocates a region and sets up an extent that you can then pass
to bus_space_alloc. How many of the different bus_space
implementations are as simple (read fast) as for i386?
