iptables on amd64 kernel

[Jakub Nadolny <jakub.nadolny@ite.pl>]

Hi,

I have just upgraded my hardware to AMD64 and installed kernel-image
2.6.8-11-amd64-k8. So all packages remain in i386 version. Everything
works fine, but iptables does not work:

# iptables -L
iptables v1.3.1: can't initialize iptables table `filter': Bad file
descriptor
Perhaps iptables or your kernel needs to be upgraded.

Kernel and iptables upgrade did not help. Can I ask you for help? 
What should I do to have iptables running with amd64 kernel?

I have installed also iptables_1.3.1-2_amd64.deb (with --force-all), but
result is the same.

I use Debian testing.

Thank you in advance!
Jakub
