I installed the lastest available kernel version on sabayon-weekly repository.
sha1sum /lib/firmware/radeon/RV770_smc.bin

Whem booted with radeon.dpm=1 as a kernel parameter on grub, screen flicks:
jumps down some pixels and go to normal position every ~4 seconds very fast.
Whem /sys/class/drm/card0/device/power_dpm_force_performance_level is changed
to "high" or "low" flicker stops. Whem is changed back to "auto" flicker
happens again, no mather what value is power_dpm_state.
Whem booted without radeon.dpm=1 parameter there isn't flicker.
