I have done the following test: 1) remove the powernowd package 2) Reboot and check CPU throttling When I log into Gnome, I get a warning that CPU frequency scaling is unsupported. powernow-k8 is not loaded. 3) Install the powernowd package. The installation tries to start CPU frequency scaling and warns that it is not supported. This is from /etc/init.d/powernowd 4) Reboot and check CPU throttling Again, when I log into Gnome, I get a warning that CPU frequency scaling is unsupported. powernow-k8 is not loaded. 5) Change line 76 of /usr/share/powernowd/cpufreq-detect.sh to 15|16) 6) Reboot and check CPU throttling No warning, CPU frequency scaling works, powernow-k8 module is loaded.
