I'm not positive - but I think my bios can take care of it automatically - full speed on AC and clocked down on battery - if the OS doesn't try to interfere. I'll test it. I believe that is what was happening in FC3 and FC4 - where the clock speed definitely did change, but was at ~ 700MHz when on AC. My bios is too old for proper ACPI support (at least fc4 would always say so in /var/log/messages - fc5 doesn't seem to)
