I just tried this with iptables 1.3.5, linux-2.6.16-xen:

iptables -A INPUT -p tcp -m tcp \
          --tcp-flags FIN,SYN,RST,PSH,ACK,URG SYN,ACK -j DROP

and it works.

Not sure this is relevant but while attempting to add ipset support I 
got the same error message. It turned out that my kernel and modules 
were out of sync.

Hope that helps, :m)
