*@author: Valentine Sinitsyn (Valentine.Sinitsyn@usu.ru)

|
*@todo: We assume that cpufreqd is in dynamic mode when applet is started because as for now it has
|
|
* no means to detect mode. This could lead to inconsistency if, ex. applet is restarted after making
|
|
* some changes to cpufreqd state.
