I did the work on freebsd 10.0 a while ago, I had a working image (worked for me anyway). I think I ported all the patches , but would need to check.
the ipfilter patch you refer to, is the patch to upgrade ipfilter from the default in freebsd 8.x to 4.1.34 . It's not relevant in freebsd 10, as freebsd 10 uses ipfilter 5.x (which is quite different , hence all the changes I had to make to get freebsd 10 working)
