  72           This option saves power, but assumes all drivers are
  73           using the clock framework. Broken drivers that do not
  74           yet use clock framework may not work with this option.
  75           If you are booting from another operating system, you
  76           probably do not want this option enabled until your
  77           device drivers work properly.
