ipfw2 dynamic rules broken?

[Yury Tarasievich]

I strongly suspect ipfw2 dynamic rules support got broken somehow. In 
1.2_STABLE, I made a trivial setup using dynamic rules with ipfw1, and it 
worked. Then I noticed I was using ipfw1, and followed the standard procedure 
for switching to ipfw2, and now my setup doesn't work anymore! Dynamic rules 
do not show in ipfw -d list, and have no effect, too.

The setup was :
allow tcp from any to me dst-port 22 setup limit src-addr 2
allow ip from any to any

Some hint, anybody, please?
