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.

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