INTEL ATOM CPUFREQ DRIVER
Does anyone know definitely if speedstep is included in the D processor?

What kind of Intel Atom do you have? I do confirm that 'dmesg grep pstate' outputs nothing intel atom cpufreq. Wheezy simply lacks power management features for that CPU. You should switch to a newer distro, Crunchbang is not supported anymore anyways.

Without HWP, this P-state selection algorithm is always the same regardless of the processor model and platform configuration. It is similar to the algorithm implemented by the generic schedutil scaling governor except that the utilization metric used by intel atom cpufreq is based on numbers coming from feedback registers of the CPU.
Avoiding CPU Speed Scaling – Running CPU At Full Speed
Isn't this boost not intel atom cpufreq the problem? For Intel core processors, intel atom cpufreq should be selected as default. One important property of turbo P-states is that they are not sustainable. More precisely, there is no guarantee that any CPUs will be able to stay in any of those states indefinitely, because the power distribution within the processor package may change over time or the thermal envelope it was designed for might be exceeded if a turbo P-state was used for too long. In turn, the P-states below the turbo threshold generally are sustainable.
The pstate power scaling driver is used automatically for modern Intel CPUs instead of the other drivers below. This driver takes priority over other drivers and is built-in as opposed to being a module.
You can use the same user space utilities with this driver, but cannot control it.I've got an Intel Atom based system but I've had no luck with cpufreq. /kernel/ arch/x86/kernel/cpu/cpufreq/): No such device. Additional control for modern Intel CPUs is available with the Linux Thermal Daemon (available as speedstep-lib, CPUFreq driver intel atom cpufreq Intel SpeedStep- enabled processors (mostly Atoms and older Pentiums (before III)).
