installing xfce4-power-managment on Sabayon 10 K edition

[setjmp]

I installed xfce4-power-manager on a Sabayon 10 KDE edition installation and got the following warning:

* Checking for suitable kernel configuration options...
* CONFIG_TIMER_STATS: is not set when it should be.
* Please check to make sure these options are set correctly.
* Failure to do so may cause unexpected problems.

Is there a way to turn on this switch using entropy? Or must I compile a new kernel using portage?
