When I use the opensource driver for my ATI card the notebook fan is always spinning and temperature of outgoing air from fan is very high, even when I set /sys/class/drm/card0/device/power_profile to low and cpu mode to powersave. With proprietary drivers (fglrx) I set video card performance to "ondemand" (I forgot the exact name of this mode in ATI control center) and cpu mode to ondemand, and the notebook isn't hot, fans are not spinning (if I don't start flash, games or some similar app with high cpu load). So with fglrx I can use the notebook on battery for 1.5 - 2 hours and it's not hot, but with the opensource driver notebook on battery is dead in 50 minutes, the fan is always on, it noise is loud, and the notebook is very hot.
