The KAME stack, as it exists in FreeBSD, requires INET support for INET6 to work. I don't know if there has been work in KAME to change this. It is certainly possible to have FreeBSD runnign without IPv4 being configured. For example, I have a router where IPv4 is only configured on the loopback interface. I noticed that things like ntpd can still recieve IPv4 multicast/broadcast packets even if you don't have IPv4 explicitly configured on an interface. I use ipfw to stop any broadcast/multicast traffic from getting in.
