I suppose, it is the "Option="-q" in the /etc/init.d/powernowd-Script, isn`t it ?? Or is there another way, to change the behavior ?
I read in the documentation, that a file can be written in /etc/default/ called "powernowd", but I do not know, what content must be in it. Do you have an example ? I suppose, to edit the script in /etc/init.d/ should work to.
