I'm absolutely sure: Using the hardware feature of today's CPU
Architectures available out there.
Command line tools have worked very well for about 3.0 (probably way
more) years. The Kernel has had APM, ACPI or PMU support for even
longer.
My Core2Duo idles down to 800MHz when I'm on battery and I don't need
the full *POWER* of my Intel(R) Core(TM)2 Duo CPU T7500 @ 2.208GHz. I
get much longer battery life. (please read this paragraph in the Voice
Darth Vader uses to say to Luke: You don't know the power of the Dark
Side!)
On Debian I'm using package cpufreqd and cpufrequtils.
cpufrequtils: former location for info (since the Kernel.org bust up its
no longer there and I'm to lazy to finger out what it is)
http://kernel.org/pub/linux/utils/kernel/cpufreq/cpufrequtils.html
cpufreqd:
http://sourceforge.net/projects/cpufreqd
If you research a bit, you'll find that these project and utils have
existed *SINCE AT LEAST* 2003 (that is 9 years. minimum)
