Sure, here it is. :^)

The CPU mostly stays in powersave mode, at 57% if on mains, and at 28% if on
battery. When the CPU load goes over 80% it switches to performance mode and
max clock, but not if it's on battery and the charge is below 30%.

On this Asus L3000D, AMD Athlon Mobile XP 2600+, CPU temperature stays around
35°C when on battery and around 40°C when on mains (chech it with "acpi -V"),
with fan spinning slowly, while without cpufreqd it stays around 60°C and the
fan gets loud often. When it cranks for a while (like encoding songs with Ogg
Vorbis) the CPU temperature gets up to around 75°C, with the fan going mad. :^)

Also, this way I get more than 2 hours from the battery, while without
cpufreqd it's around 45 minutes.

I would avoid using cpudynd and cpufreqd at the same time, they would probably
step on each other's toes. But surely that's not what the OP meant. :^)
