The cpufreq framework is set up on Grml with the ondemand scheduler as default. When the CPU is idle, it winds the clock down to 1000mhz however you see the frequency go up to 2.2ghz when the system goes under load. This saves power, is cooler, and generally works well. cpufreq-info will tell you what governors are set, and cpufreq-set -g performance will latch the CPU at it's highest speed. I'm sure someone else has answered this by now but perhaps this response will be useful for the archives. apt-get install cpufreq-utils will get this support in a Debian-like distribution.
