pablitofuerte proposed the following answer:
As you can see... your current settings are acpi-cpufreq & ondemand
driver: acpi-cpufreq
available frequency steps: 1.60 GHz, 1.33 GHz, 1.06 GHz, 798 MHz
available cpufreq governors: conservative, ondemand, userspace, powersave, performance
current policy: frequency should be within 798 MHz and 1.60 GHz. The governor "ondemand" may decide which speed to use within this range

You have an Intel(R) CPU T2060, so acpi-cpufreq (generic module) should
be ok (if it doesn't work you can try with speedstep_centrino)

Check previous steps - lines above:
sudo aptitude remove powernowd                       # if it is already installed you can remove it (you wont need it)
sudo aptitude install cpufreqd                              # this seems to be ok
sudo aptitude install cpufrequtils sysfsutils          # installed them, if they are not already installed

sudo modprobe acpi_cpufreq                              # Ok, cpufreq-info shows that driver: acpi-cpufreq                   
#You have an Intel(R) CPU T2060, so acpi-cpufreq should be ok (if it doesn't work you can try with speedstep_centrino)

sudo modprobe  cpufreq_powersave                 #this will have
temporary effects so....

*** We need to add those modules in /etc/modules to make then load on system start:
THIS IS THE IMPORTANT PART
-------------------------------------------------------------------
echo acpi_cpufreq | sudo tee -a /etc/modules
echo cpufreq_powersave | sudo tee -a /etc/modules

You might check /etc/modules: 
sudo gedit /etc/modules
At the end of that file you should find:
acpi_cpufreq
cpufreq_powersave

** If you find cpufreq_ondemand remove it. 
--------------------------------------------------------------------
That's it.
