I looked at the source code for the sio driver but couldn't see any obvious problems with it. It seems to me that the hardware on my modem is not supplying the correct answers to the probe device test that the driver performs (The chip on my card is a WD16C450). I'd also appreciate it if anyone else has some ideas on how to fix this.
