I think you misunderstood. I'm not complaining about the technology or the kernel or anything. I possess basic knowledge of power saving techniques, underclocking, overclocking etc. So it is clear to me that it takes a while for the CPU to actually scale up when suddenly experiencing load and of course that it will take it's time to settle again, once the load is gone. Now all this is not my problem. My problem is: my device is laying flat on my desk, no apps or progs running, no exceptional background processes running, basically: there is no need to upscale. But why does it still do so and figuratively burning battery for nothing?
Laying there with Xorg eating ~3%, Conky ~1% and some hildon-stuff eating a combined 1% we are at about 5%. This is what Conky also shows: 5% CPU load. There is no need to ask 1000MHz, why and what does do so?

I know. And yes it's true, if needed it can go from 0 to 100, but also, if needed to any point inbetween those two figures. Not exactly, the steps are defined (the supported frequencies), but you get the idea...

As pointed out above, no instances asking for power. At least no obvious ones. There maybe is a process jumping in just short enough to Conky not list it but long enough for Conky to notice the jump in CPU frequency.
