That's something to _STRONGLY_ discourage. Kernel updates aren't required  
that often (if you feel they are, run one of the BSDs), and they aren't  
the cause for the original posting/pain anyways.

Running firewalls on outdated kernels is as dangerous as it can get - some  
code injection might disable your firewall and then expose your whole LAN.
