Moderately hacked pccard code from newconfig. It is somewhat in

incomplete and likely has problem.  The code was originally pcmcia,
but I renamed it to pccard and made it compile on FreeBSD -current.  I
converted SIMPLEQ to STAILQ as well as a few sc->dev.xname ->
device_printf changes.  This is a green port of fairly mature code.

I derived this work from the FreeBSD newconfig project
(http://www.jp.freebsd.org/newconfig).  Any problems with it are
likely introduced by me.
