I would suggest changing that to use __dpmi_int(). This go32 function is
actually just an alias for __dpmi_simulate_real_mode_interrupt(), which
should generally be avoided because it requires you to fill %ss, %esp,
and the flags with valid data, which __dpmi_int() will do for you.

Don't you mean dosmemget()? This will transfer data from your address
space into conventional memory, which is the exact opposite of what you
are trying to do!
