   2The cpufreq-nforce2 driver changes the FSB on nVidia nForce2 platforms.
   3
   4This works better than on other platforms, because the FSB of the CPU
   5can be controlled independently from the PCI/AGP clock.

   7The module has two options:
   8
   9        fid:     multiplier * 10 (for example 8.5 = 85)
  10        min_fsb: minimum FSB
  11
  12If not set, fid is calculated from the current CPU speed and the FSB.
  13min_fsb defaults to FSB at boot time - 50 MHz.

  15IMPORTANT: The available range is limited downwards!
  16           Also the minimum available FSB can differ, for systems 
  17           booting with 200 MHz, 150 should always work.
