自動起動のからみで、CPUモジュールを自分でインストールして、cpufreq-infoあたりを初めて知った
お暇なときはこんな感じに
$ cpufreq-info

analyzing CPU 0:
driver: powernow-k8
CPUs which need to switch frequency at the same time: 0 1
hardware limits: 1000 MHz - 2.00 GHz
available frequency steps: 2.00 GHz, 1.80 GHz, 1000 MHz
available cpufreq governors: conservative, userspace, ondemand, powersave, performance
current policy: frequency should be within 1000 MHz and 2.00 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 1000 MHz.
