Wrong. I've seen messages on bugtraq saying it is possible to "load" modules into the kernel by patching /dev/kmem. Even for loading modules custom modules the normal way the attacker needs root priviliges (unless you have a world-writeable /lib/modules...). If this is the case it is too late anyway...
