I've got to write a test program for one of our PCI cards, and it includes
about 16M of PCI-mapped memory.  I'm thinking that
__djgpp_map_physical_memory would work nicely to make that memory easily
accesible to me (is this right?).

How do I know what to pass as the first parameter, the void *our_addr?
Does it have to be allocated memory, or does it have to be unallocated?
Or does it have to be out of the range of any memory actually usable (such
as (void*)(0x01000000))?
