The same problem exists with other power saving options:
# cat /etc/X11/xorg.conf
Section "Device"
Identifier "Configured Video Device"
Option "DynamicPM" "on"
Option "ClockGating" "on"
Option "ForceLowPowerMode" "on"
EndSection
and in /var/log/Xorg.0.log:
(WW) RADEON(0): Option "DynamicPM" is not used
(WW) RADEON(0): Option "ClockGating" is not used
(WW) RADEON(0): Option "ForceLowPowerMode" is not used
--
