========^===== 1
: panic: make_dev() by driver pccard on pre-existing device (min=0,
: name=pccard0.cis)
=============^==== 0

I wonder why 
	sc->cisdev = make_dev(&pccard_cdevsw, 0, 0, 0, 0666, "pccard%u.cis",
	    device_get_unit(sc->dev));

device_get_unit is returning 0 instead of 1 for the second device.
haro-san, if you could add some debugging information to try to find
out why this is the case, that would be helpful.

My laptop only has one pccard/cardbus slot, so I didn't run into this
or even think it would be a problem...
