        Currently it is likely impossible to remove ipv6 module even
        if you are foolhardly enough to set that parameter.
        You will be able to "rmmod", but some jiffies latter you will
        get Oops..

        Main motivation was to have the ipv6 module loadable into the
        kernel after boot.  Linus had for a while modularity disabled
        entirely, but this 'unloadable' trick convinced him that "right,
        it can stay there that way." -- and let hackers to have a look
        at the problem set sometime.
