Oops... Setting the correct Port and IRQ got it attached (as sio2, doh!) I suspect that this would be a good time to write a new driver for the PC87109 family of IR ports; since in addition to IR, they have an an "Enhanced UART" mode which, among other things, can operate 13 times faster than the standard UART, and supports DMA. This brings up the strange dual nature of these devices. On the one hand they can be used as (real) serial ports, which means they need to be character devices and use a line discipline. On the other hand, since a line discipline must be fed incoming characters one at a time, it is completely impractical for high speed packet data.
