It is usually wrong to assume int86x supports any interrupts function 
which requires a pointer to be passed via the registers.  int86x only 
supports a small subset of these.  (The reasons for this are explained in 
the DJGPP FAQ list, available as faq102.zip from the same place you get 
DJGPP, section 18.1.)  You should use _go32_dpmi_simulate_int() function 
instead, because it supports ANY interrupt function.
