If I upgrade to a newer kernel, it says 1ghz in idle and 1,8ghz in full load (I wonder it takes the fsb value, that is 200mhz, directly form cpu and not from the bios, so it assumes 200x5 in idle and 200x9 in full load) flapane@a64:~$ cpufreq-info cpufrequtils 002: cpufreq-info (C) Dominik Brodowski 2004-2006 Report errors and bugs to linux@brodo.de, please. analyzing CPU 0: driver: powernow-k8 CPUs which need to switch frequency at the same time: 0 1 hardware limits: 1000 MHz - 1.80 GHz available frequency steps: 1.80 GHz, 1000 MHz available cpufreq governors: userspace, powersave, ondemand, conservative, performance current policy: frequency should be within 1000 MHz and 1.80 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency is 1000 MHz. analyzing CPU 1: driver: powernow-k8 CPUs which need to switch frequency at the same time: 0 1 hardware limits: 1000 MHz - 1.80 GHz available frequency steps: 1.80 GHz, 1000 MHz available cpufreq governors: userspace, powersave, ondemand, conservative, performance current policy: frequency should be within 1000 MHz and 1.80 GHz.
