Ja pouzivam skriptik, ktery obsahuje neco jako toto (hlavne 
ten radek se scaling_max_freq je dulezity):

# high:
echo performance > /sys/devices/system/cpu/cpu$i/cpufreq/scaling_governor
echo 1667000 > /sys/devices/system/cpu/cpu$i/cpufreq/scaling_max_freq 
echo 0 > /proc/acpi/processor/CPU/throttling

# low:
echo powersave > /sys/devices/system/cpu/cpu$i/cpufreq/scaling_governor
echo 1000000 > /sys/devices/system/cpu/cpu$i/cpufreq/scaling_max_freq 
echo 4 > /proc/acpi/processor/CPU/throttling

Je potreba to udelat pro kazdy procesor (core) zvlast - viz 
promena $i. U me jsou procesory: 0 1.
