This could still make some sense, if these GPIO pins on the 264-side cartridge are connected to some control signals inside the 1551. It certainly makes some sense to control the 1551 /RESET signal from the 264. I am not so sure about /IRQ, and I guess that in this case, O2 would have to be something else than Phi2. I guess that your best bet is to check MESS, hoping that it really emulates the interface, instead of faking it with some hooks.
