You found your problem, then.  When you use iptables -m state, it loads the
state module.  Since it's not compiled as a module, it won't load.  Either
change it to module in the kernel or remove the -m state (I think I tried
once compiling into the kernel and dropping the -m state, but it didn't
work).
