I'm running Ubuntu 9.04 on relatively old laptop with ATI Mobility x600 inside. On the last version of Ubuntu, when I was able to run proprietary fglrx driver, I was able to slow down graphic card by aticonfig --set-powerstate 1 and save some battery charge. Now I forced to run open source driver as ATI decided to drop support for old cards. But I can't find a way to control power states now except relying on DynamicClocks option in xorg.conf.

But I really know better when and what powerstate I want, so is there a tool that let me change power state manually or at least let me somehow change the behavior of automatic power state selection?
