Iptables problem

Hi I'm trying to install Kernel 2.4.7.SuSE. The kernel is compiled, and ready. Iptables 1.2.2 from cvs has been installed. When booting, SuSEfirewall2 comes up with a lot of error-messages saying, that either my kernel or iptables should be updated. Please anyone know how to fix this? Jaska.
