8255.c and other modes

Hi All;
 I'm writing a bus emulator to set on a unibus like data bus. I really need interrupts to do this, and management has decided that we shall use NI PCI-DIO-96 as the interface card.

 Is there any reason that the 8255 driver doesn't do more then mode 0? In the ni_pcidio source file it sure looks like interrupts are supported, is that only from the timers on the card?

Thanks
