I don't have any CentOS4 box handy to check it out, but it seems like the kernel module is missing. Netfilter has two component, userspace (in /lib/iptables) and kernel (in your kernel's directory under /lib/modules). The userspace as packaged by Red Hat often has many more modules than actually supported by kernel.
