What i have understand from ur question is that u do
not need to upgrade ur kernel but remove ur previous
ipchains/firewall completely.
Follow these steps

*First 
do lsmod
if u see that ipchains module is present then
do 
rmmod ipchains 
(i m supposing that previously u have ipchains
firewall in ur linux box)

*if u completely want to get rid from ipchains remove
its rpm

* now insert module of iptables
by using
insmod iptables
if it works
add other modules of iptables.

* now apply iptables  rules . hope now it will not
give u resorse busy error
