I had to back this out globally as we weren't able to fix it. In the 
meantime I have come up with a partly reworked patchset, which does no 
longer panic for me.

If you have some time and use dummynet, divert(+natd) or ip_fastforward 
(sysctl net.inet.ip.fastforwarding=1) I'd appreciate if you could give it 
a try: http://people.freebsd.org/~mlaier/mt_tag_remove.diff

Thanks.
