I suspect you will get almost the same behavior by using this hack and leaving it to the kernel to scale it: #!/bin/bash modprobe cpufreq_userspace echo $$ > /var/run/mycpufreqd echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor It will jump to the highest frequency when the load is high, and drop to the lowest frequency when there is less load. See for example <URL: http://www.mjmwired.net/kernel/Documentation/cpu-freq/governors.txt > for documentation on the various governors.
