[ltp] t42 archlinux fan noise

[Arian Kuschki]

After installing laptop-tools and cpufreq and adding them to my start up 
daemons my temperature when idle is down to 41 degrees and the fan is at 
around 3000. I vaguely remember at least laptop-mode to be active in 
Ubuntu by default, so that may explain the difference I experienced.

I will investigate the other options that were suggested, e.g. powertop, 
but for now I am happy that the fan is significantly quieter. 

Thanks everybody for your help
Arian
