The problem is not with the Gnome frequency scaling applet. I used the cpufreq-selector command and it doesn't change the frequency either. I managed to get some reaction yet, by switching the ACPI daemon and related on and off quickly. Then, sometimes, for a few seconds, the frequency will

Well that was indeed the problem. Once the custom kernel was running, with the CPU frequency throttling simply and basically turned on, there was no more problem. The low frequency and power saving governors ran perfectly. On the other hand I had no more Wi-Fi. 'Going to try to solve that one
