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.
