Ondemand, the same as what appears in the applet, after boot. However,
despite "Ondemand", even a huge CPU load does not make Debian asking
for more CPU resources, such as 100%.

As I explained before, there is no modification about CPU frequency,
even with a maximum load.

How could I modify it?

Ondemand, okay, but how to modify this?

My aim is not to save power. I am running many scientific-purpose
applications, and they need full CPU power. As I often switch between
many OSes, manually modifying manually governor is tedious. I
installed kpowersave, and it works, but I am pretty deceived that it
does not work with GNOME's utils.
