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"; 
        action "kldload if_wi";
};
# grep -C1 \$pnpinfo /etc/devd.conf
nomatch 0 {
        action "logger Unknown device: pnp=$pnpinfo loc=$location bus=$bus manufacturer=$manufacturer product=$product";
};
# devd -dD

Looks like:

- bus name does not substituted, see "Testing bus= against
^pccard[0-9]+" messages, kernel reports valid messages:
pccard0: <unknown card> (manufacturer=0xffffffff, product=0xffffffff) at function 0
pccard0:    CIS info: Shining, PMIDE-ASC, Rev 1.04
pccard0: <unknown card> (manufacturer=0x0156, product=0x0002) at function 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=$manufacturer product=$product", but
default devd.conf does not works also.
