I've done something similar since I'm using the bootp stuff & mfs root.
I added a SYSINIT to do the bootp call if nfs is not being used.  I also
added code to specify which adapter to send the bootp requests on in case
of multiple controllers.  What I've been stumped on is trying to do a 
bootp request on all interfaces until success.  This might be the
wrong thing to do.

BTW I hacked up the Linux etherboot code to be able to tftp the kernel
and boot FreeBSD again.  This way I can do netboots over Intel 10/100B 
cards.  However now I'm running into a problem with machines locking up
with a non-trival compile.

I hope to get this code cleaned up since I've been gross hacking stuff
to get things to do what I need.

BTW anyone know how to pass a string in via a #define in config?
