It is actually only _8_ bits. The IR input is preprocessed by an MSP430
microcontroller on the card, which presumably reads its code from the
EEPROM chip right next to it. AFAIK, there is _no_ way to access that
EEPROM (nor the MSP430 for that matter) through the PCI interface. There
should be a JTAG interface soldered on the board next to it, through which
it should be possible to read the EEPROM (and reprogram it).

So if you have the equipment, read that EEPROM (I'd like to have a copy of
its contents, BTW), reverse-engineer it and see if you can change it so
that it works the way you want it.
