While the mode of operation you describe is the default behavior, please note 
that /etc/rc.firewall ends with:

         if [ -r "${firewall_type}" ]; then
                 ${fwcmd} ${firewall_flags} ${firewall_type}
         fi

If you set firewall_type to the name of a file,ipfw will happy read one rule 
per line from that file via a pre-processor like cpp (or cat)...
