By downloading a kernel, POM-ng (patch-o-matic-ng) and an older POM-ng that
still has the string patchlet, and iptables. Patch the kernel using the older
POM-ng for the string match and use the newer POM-ng for recent stuff. Install
the new kernel and iptables and see if everything (still) works.

If you've never done this I suggest you search the internet for howto's, read
the README's and/or INSTALL files and try it with a test-PC first.
Howto's on patching a kernel is not really the scope of this list.
