Version:           4.6 (using KDE 4.6.3) 
OS:                Linux

In KDE 4.4 it was easily possible to switch the governors (ondemand, powersave, etc) by checking corresponding options in the KDE Powersave Settings. In 4.5 one had to write in KDE Powersave Settings a short command to do it via Solid framework in order to do the same thing. Now, in 4.6, it is necessary to write a separate script for each governor (using sudo or/and granting root privileges to certain files). Since it is an obvious regression in useful (mostly for laptops) features, I'd like to get it back.
Moreover, there are only 3 possible profiles are left. For example, "Presentation" was removed, though it served very well exactly for presentations.

Reproducible: Always

Steps to Reproduce:
Goto KDE Powersave Settings - Power Profiles.

Actual Results:  
One needs to write a script (one line in the box is not enough, since many people have dual- or multiple-core CPUs, so one has to address each core separately).

Expected Results:  
Return to 4.4-like or create a similarly functioning subsystem.
