First, don't use `int86'; use `__dpmi_int' throughout.  `int86' has some 
subtle aspects regarding the 32bit/16bit registers issues which might be 
the cause of your problems.

Second, I think you should use _go32_dpmi_allocate_real_mode_callback_retf 
instead of _go32_dpmi_allocate_real_mode_callback_iret, since the mouse 
driver expects far function, not an interrupt handler.
