    it's all nice code and such, but I still wonder why this can't be done
    by a userland policy daemon. The 2.6 kernel has the infrastructure to
    give very detailed information to userspace (eg top etc) about idle
    percentages...... I didn't see anything in this driver that couldn't be
    done from userspace.

    Note that I'm not totally against doing some of this in the kernel; I
    can well see the point of say, detecting an IRQ overload and based on
    that, go to max speed in the kernel because it's a situation where
    userspace doesn't even run; but the patch as is doesn't do any such
    advanced things...
