Oops, looks like there is some bugs here:
# cat /etc/devd/atacard.conf
nomatch 10 {
match "bus" "pccard[0-9]+";
match "function_type" "4";
action "kldload atacard";
};
# cat /etc/devd/wi0.conf
nomatch 10 {
match "bus" "pccard[0-9]+";
match "manufacturer" "0x0156";=20
action "kldload if_wi";
};
# grep -C1 \$pnpinfo /etc/devd.conf
nomatch 0 {
action "logger Unknown device: pnp=3D$pnpinfo loc=3D$location bus=
=3D$bus manufacturer=3D$manufacturer product=3D$product";
};
# devd -dD

Looks like:
- bus name does not substituted, see "Testing bus=3D against
^pccard[0-9]+" messages, kernel reports valid messages:
pccard0: <unknown card> (manufacturer=3D0xffffffff, product=3D0xffffffff) a=
t function 0
pccard0: CIS info: Shining, PMIDE-ASC, Rev 1.04

on 0
pccard0: CIS info: Lucent Technologies, WaveLAN/IEEE, Version 01.01
- variables does not interpreted, see "nomatch 0" entry above, I've
extend it with "manufacturer=3D$manufacturer product=3D$product", but
default devd.conf does not works also.
