Hi Warner,

Sorry for the late responce, and thanks for your quick fix.
I've confirmed that panic has gone away, and two /dev/pccard?.cis
devices created.

$ ls -l /dev/pccard*
crw-rw-rw-  1 root  wheel    0,  40 Sep 21 21:19 /dev/pccard0.cis
crw-rw-rw-  1 root  wheel    0,  41 Sep 21 21:19 /dev/pccard1.cis
$

Thank you,
  Haro
