If I understand correctly it uses sysfs interface and requires 2.6 kernel. Once started it monitors cpu load and increase or decrease mhz's depend on load. My mobile celeron (P4) uses seven steps, if system is idling mhz will drop to 187mhz and from that it increased step by step til the max which is in my case 1.5ghz, seven steps then between 187mhz and 1500mhz. I haven't got any errors yet but instead I have got longer battery life and decreased heating. -- best rgds ~tt
