[CentOS] running 2.6.19 on centos 4.4

Hi all,

I had to take a machine and compile 2.6.19 on centos 4.
I started with /boot/config-2.6.9-34.0.2.ELsmp. Everything works fine 
except on boot
I get the following error for iptables:

Applying iptables firewall rules: iptables-restore v1.2.11: 
iptables-restore: unable to initializetable 'filter'
Error occurred at line: 3
Try `iptables-restore -h' or 'iptables-restore --help' for more information.
                                                           [FAILED]

Have I not included something in the kernel?

Thanks,

Jerry
