Comment 3 for bug 60439

Like Lumir proposed i compiled a fresh kernel and iptables patched against patch-o-matic.

First I had the same problem as Yota : iptables : No chain/target/match by that name

After googling some minutes i've applied this little patch on sources in KERNEL_DIR/net/ipv4/netfilter/ipt_connlimit.c
: http://lists.netfilter.org/pipermail/netfilter/2007-April/068386.html et recompiled/reboot again on the new kernel

I hope this trick could have helped you
