  84           This option saves power, but assumes all drivers are
  85           using the clock framework. Broken drivers that do not
  86           yet use clock framework may not work with this option.
  87           If you are booting from another operating system, you
  88           probably do not want this option enabled until your
  89           device drivers work properly.
