The iptables version is irrelevant in these cases - only the kernel and
its version counts. I can think of two possibilities (therefore stressed
the question on from where did you get the source of the running kernel):

- you run a vendor-provided kernel, compiled from vendor-provided source
- the additional patches you applied break some internal mechanism in
  netfilter

I know it's not much help for you.

Jozsef
