Report errors and bugs to linux на brodo.de, please.
analyzing CPU 0:
  driver: p4-clockmod
  CPUs which need to switch frequency at the same time: 0
  hardware limits: 113 MHz - 900 MHz
  available frequency steps: 113 MHz, 225 MHz, 338 MHz, 450 MHz, 563 MHz, 675 
MHz, 788 MHz, 900 MHz
  available cpufreq governors: ondemand, performance
  current policy: frequency should be within 113 MHz and 900 MHz.
                  The governor "performance" may decide which speed to use
                  within this range.
  current CPU frequency is 900 MHz (asserted by call to hardware).
