If you need two working parallel ports then you can build a new kernel.

In the mean time the above config will (if I still understand the config
search rules) find the first port in the same way the BIOS will and then
stop looking for more.

I think it's important that the GENERIC kernel find the "right" (as per
the BIOS) first port, and I don't see that it should have to support
more than one port by default.

I've never been able to get the polled device to work on my IBM PC
Server 325.  I've never tried on any other kind of machine.

Mind you I haven't yet tried with the interrupt driven variant either,
though since the interface is going to be delivering interrupts anyway I
can't see how it'll work any worse!  ;-)
