I've just found out where the problem is. In 2.6.20-rc1 changelog the following thing was modified: [TCP]: Don't set SKB owner in tcp_transmit_skb(). That seems to break the owner-match for TCP packets. I was able to undo the change with the attached one-line patch which fixed the problem for me. Greets Sebastian.
