There have been talks about doing something similar to the FreeBSD parport-bus,
but obviously interest in parallel thingies has decreased (first with the 
advent of pcmcia, now even more with USB).

I'm remotely interested, as I've used PLIP, a DCF77 receiver and somewhere
have a DLINK 620 ethernet adaptor that was meant to be used with NetBSD, but
now that notebook has retired completely and been replaced with a PCMCIA
capable one.
