It basically installs several kernel patches and then requires a recompilation of the kernel. You'll need the kernel and iptables sources and the POM package. Unpack POM and run it. The POM will then give you a text-based "wizard" that prompts you about which patches you want to install. It then patches the kernel. You then need to compile the kernel. The catch here being that you need to go into the config and make sure that the iptables options that are necessary to support your patches are selected. Once you finish compiling and installing the kernel and it's modules, you should have the new iptables extensions available after rebooting.
Here's the HOWTO that I've used:
