If you start the appled / add it to the panel it starts with CPU0 (default) and reads the list of available frequencies from 

/sys/devices/system/cpu/cpu1/cpufreq/scaling_available_frequencies


If you change the CPU to monitor then it seems not to read the available frequencies again.
If you select a frequency from the applets list where you know the different frequency should be instead or if you manually select it by writing it to "scaling_setspeed" the appled is displaying it correctly in the panel but still shows the wrong / old list in the drop-down menu.


This *could* affect users with multi-cpu systems ( untested bacsue I have none ) and users that are able to alter the frequencies on a multi-core system ( tested ).

Looks like that (can not make screenshot when drop down menu is showed)
