It's loaded from the ipfw.ko module.  You can build modules for some
things that are compiled in using 'options'.

You will probably need to just include IPFW and IPDIVERT in your
kernel config for this to work.

sys/conf/NOTES and sys/<arch>/conf/NOTES

You can add 'makeoptions NO_MODULES=yes' to your kernel config to have
it only build a kernel and no modules.
