    And, thus, we decend into more /proc crappyness.

    After *lots* of discussion and months of waiting, it was decided between
    Alan, David Jones, Jeff Garzik, and other affected parties that
    /proc/sys/cpu/#/whatever would be a reasonable. It has even appeared on
    lkml a couple of times in the past.

    Currently, there is an allocated sysctl number in include/linux/sysctl.h
    for /proc/sys/cpu, and it is used by the cpufreq code to provide:

    /proc/sys/cpu/#/speed
    /proc/sys/cpu/#/speed-max
    /proc/sys/cpu/#/speed-min

    However, it's true that some of that needs to be pulled out so anything
    can use /proc/sys/cpu/#. Just takes the necessary parties to get together
    to do the hard work, and with the right hardware to test it out.
