OTOH, this may be a kernel issue. There have been some changes recently
which updated some counters from 32 bit to 64 bit ;-> Clearly this
will break the ABI and will give crap stats.

Try also if you can kernel 2.6.10.
I think weve narrowed down iptables to be working if <= 1.2.11
It will help me if you can narrow down the iproute2 version as well
as the kernel version where things start breaking.
