I have never tried anything like that, but I think this is
impossible. The first bytes of the callback are used by the callback
code itself, and the callback is created by the DPMI server.
So the only feasible way to achieve this would be to bypass the
callback and _go32_dpmi_allocate_real_mode_callback_retf entirely, and
instead to write your own real-mode handler in assembly.
