Why not put your new device in DEVS: called serial.device and rename the
existing one to amiga-serial.device. Then an open device of serial.device
will get yours and an opendevice() of amiga-serial.device will get the amiga's.

->OpenDevice() call to do the actual opening (I merely need to

I believe it is, although I personally haven't tried it.
