This is a little bit off-topic, but I set the rc.conf(5) dumpdev
variable to "AUTO".  This should work (this is from rc.d/dumpon) :

%%%
        case ${dumpdev} in
        [Nn][Oo] | '')
                ;;
        [Aa][Uu][Tt][Oo])
                while read dev mp type more ; do
                        [ "${type}" = "swap" ] || continue
                        [ -c "${dev}" ] || continue
                        if /sbin/dumpon -v "${dev}" 2>/dev/null; then
                                # Make a symlink in devfs for savecore
                                ln -s ${dev} /dev/dumpdev
                                return 0
                        fi
                done </etc/fstab
%%%

Nevertheless, when my box panices, it drops to DDB and I always need to
call doadump() manually.
