the following URL gives you the change that was made to make the OLD
version of dummynet Vimage compatible.

http://p4db.freebsd.org/fileLogView.cgi?FSPC=//depot/projects/vimage/src/sys/netinet/ipfw/ip_dummynet.c

does this still apply to 8.x? or did you redo the dummynet in 8?
if you didn't it may be worth looking to see if these changes apply to 
8.x real soon before it's frozen.
