dmesg

I don't know why and where, but open source driver is consuming more power than with catalyst for about 2-3 watts. For example, if switchoff display, and don't touch notebook, wia ssh I see powertop says with catalyst use only 4.43 watts, and with radeon it usualy closer to 7 watts. DPM is enabled, hdmi is disabled, battery profile is activated... See dmesg output.
