Load the ipv6 module with disable=1, which is why I added it :)

>From Documentation/networking/ipv6.txt:

disable

        Specifies whether to load the IPv6 module, but disable all
        its functionality.  This might be used when another module
        has a dependency on the IPv6 module being loaded, but no
        IPv6 addresses or operations are desired.

        The possible values and their effects are:

        0
                IPv6 is enabled.

                This is the default value.

        1
                IPv6 is disabled.

                No IPv6 addresses will be added to interfaces, and
                it will not be possible to open an IPv6 socket.

                A reboot is required to enable IPv6.
