No, there is a way now as the open source ATi driver now supports KMS.
# echo low > /sys/class/drm/card0/device/power_profile
^^ do this and your card will instantly switch to low power + low fan speed mode. There are "low" "mid" "high" "auto" and "default" modes.
But this will be temporary and you'll have to do this every time you reboot. For this, add the above line to /etc/rc.d/rc.local which will execute it every time at boot.
Note: rc.local is not packaged by default in Fedora 16. You'll have to create it yourself.
Alternatively, you can also switch to dynamic load based switching by:
# echo dynpm > /sys/class/drm/card0/device/power_method
but this is a bit problematic. So stick with "profile" in the power_method and "low" in power_profile.
