First stab at fixing resource deallocation, and implementing fdc(4) as

a KLD.  Still doesn't work well except in the PCMCIA case (now if only
pccardd(8) could load and unload drivers dynamically...).  Mainly, it
tries to find fdc0 on the PCI bus for whatever obscure reasons, but i
need someone who understands driver(9) to fix this.  However, it's at least
already better than before, and i'm tired of maintaining too many private
changes in my tree, given the large patches bde submitted. :)

Idea of a KLD triggered by:	Michael Reifenberger <root@nihil.plaut.de>
