    Have I said power doesn't matter on AC?
    Do you agree that a datacenter has different performance vs power
    tradeoff demands as a battery driven mobile device?

    Back to the topic:
    As you did not answer on my (several) sysfs knob request(s), I expect
    you agree with it and will add one.

    It's not only for real usage, but to give people a chance to easily
    test and get feedback on different HW.

    Thanks,

    Thomas
