That is indeed great news Alexey. Are you using the dynamic (dynpm) power management support or the profile-based power management support? I profile-based, which profile?
Now for the bad news. I have just learned that there is a serious regression in the 2.6.38 kernel used in Natty (the same kernel which contains the performance improvements I mentioned in comment #23): compared to Ubuntu 10.10, the power consumption on Ubuntu 11.04 for mobile devices is up about 10% on average but under some workloads, the power consumption is up by nearly 30%. This is unrelated to the ATI power management support or the ATI performance improvements as it occurs with Intel / ATI / NVIDIA graphics, but rather is elsewhere in the kernel and has occurred since 2.6.37. It is also still not fixed in 2.6.39-rc4.
