What you could do pretty simple, is add the standard pccard.conf from a 
FreeBSD install. You could either do this on-the-fly with exec.php and 
then killing the pccard daemon, or you could build it into the image
itself.

For your comfort, I've put the /etc/default/pccard.conf for a standard 
4.9-RELEASE online at http://dwaalspoor.org/pccard.conf.
------------------------------

Since I can't get remotely onto the machine (both NICs are not working)
I can't use exec.php. And I am not sure how to rebuild the image.
Are there instructions? I am using the generic-pc-1.0.
Is there someone out there who can build an image with the updated
pccard.conf without too much trouble? They can e-mail it too me (my box
is unlimited) and I can host the file for anyone else.

Thanks in advance,

Subject: Problem with PCMCIA Cards

I have an IBM 365XD with two "Xircom CreditCard 10Base-T ``CreditCard
Ethernet Adapter IIps'' (PS-CE2-10)" cards. According to the FreeBSD
Hardware Compatibility Guide, they are supported, however when I boot
m0n0wall, and hookup the cards to the network, there is no link light on
either card.
From boot message I can see that the PC Card slots are being detected,
and that it says there are cards present on pcic0. However when it tries
to "Starting PC Cards..." it does don't detect anything (not sure if
this is normal). After boot is complete LAN -> sis0 and WAN -> sis1, and
if I try to re-assign it to xe0 or xe1 it says it's an Invalid
interface.

Any ideas?
