Yes, I'm using Xorg 6.8.2 (-10 from Ubuntu), and the xorg driver does have 
power saving options, although they are not on by default (it's the 
DynamicClocks option). The proprietary drivers enable it by default. My 
preliminary experiments seem to show that you can save further by 
underclocking the radeon card (a Mobility in my case).
