Are those values bad/wrong? They look a bit high, maybe is that you card is
not capable of running/applying those power savings profiles? :-?
Anyway, you have more info on how to tweak the power settings of the ATI card
(when using KMS and radeon driver) here:
https://wiki.archlinux.org/index.php/ATI
If one method does not work, try with another until you find one that likes you,
but also keep and eye on the temperatute of your notebook.

Playing with vga drivers is always risky and the first step for problems to arise.
You will have to evaluate your current situation, if you can afford having the fan
always on then consider trying the ATI drivers.
If you compile upstream drivers, just ensure to disable KMS, maybe that's enough
and you won't need to remove radeon driver at all. If you use Debian stock ATI
closed drivers, they will take care of disabling KMS for you.
