    I think this is a bit too heavy-handed.
    That thing adds a lot of noise to the sound,
    but it doesn't really prevent the driver from
    working properly. And perhaps there are
    other options with the same effect?
    Also, that would motivate people to
    optimize DEBUG_PAGEALLOC, while otherwise
    they wouldn't know. :)

    What is the problem with the warning
    exactly? If it makes problems, we can
    just remove it and update the help text
    instead, for example.
