These values are normally returned from other real-mode calls.  For
example, some drivers have an int 0x2f that you do which returns a far
pointer to their regular API.  This pointer is a real-mode
segment:offset pointer.  These are the values that you pass to
_go32_dpmi_simulate_*.

These segment values are *not* protected-mode selector values.
