Note that it's complaining about the kernel modules, not the firewall. I 
had this problem way back with FC1, and traced it to some module not 
managing reference counts properly. IIRC there were issues with safely 
unloading the module so the decision was to make the initscript not unload 
modules by default.

I'm still running FC2 and at the bottom of /etc/sysconfig/iptables-config I 
have:

# disable unloading of modules
