I doubt it's all due to just that, but FWIW one thing you can try is radeon.dynclks=1 to enable clock gating.

Created attachment 60410 [details] drm output from kernel.log Hi, Archlinux running on a compal CL56 (radeon mobility 9700). kernel is 3.2.11 and I can't find any file for power management : - /sys/class/drm/card0/device/power_method doesn't exist and can't be created - /sys/class/drm/card0/device/power_profile doesn't exist and can't be created Please find attached drm output from kernel.log. Apart from that it's working fine but the lack of power management reduce the run from a battery from 4h to 1h30.
