look at the following document:

http://perforce.freebsd.org/fileLogView.cgi?FSPC=//depot/projects/vimage/porting_to_vimage.txt

sorry if that wraps

there are patches at:

also look at the patches in the ipfilter files in that branch.

If you are doingthe work for zones then that will be applicable.

BTW you might look at dropping all teh suport for freeBSD 3.x in
your files :-)
the aggregate diff can be found at:

If you want to handle ipfilter yourself then we'd be happy to let you 
do it.
