problem with connlimit module compile

[Keith]

I'm using kernel 2.6.13 and iptables 1.3.2 and 
patch-o-matic ng-20040621

I'm getting an error when I try to patch and compile to use 
connlimit from the patch-o-matic base. the errors look like this:

In function count_them:
struct ip_conntrack_tuple_hash has no member named ctrack

And sure enough I find the ctrack pointer was removed here:

I started digging into the source and find it non-trivial
Any suggestions on a work around?
