pmap, mmap, iomap... what unixes are these available on?

We're looking at un*x's to move our application to, but we need
to be able to memory map a register based board we produce
into a processes address space. HP has iomap. Sun has mmap
which I presume can do the same thing. Regulus has a non-standard
call that does this. Concurrent does it with mmap.
Does anyone know if AT&T can do this with the latest SYSV/386?
How about other un*x's?
			Thanks in advance...
