For systems with Radeons, it is probably better to use radeontool from ports. It reportedly reduces power consumption below the levels seen with the DPMS patch and also allows you to power down the DAC for the video connector. You do need to add it to rc.suspend and (most important) to rc.resume. I just add: if [ -x /usr/local/bin/radeontool ]; then radeontool light off|on radeontool dac off|on fi depending on whether it's the suspend or the resume file. If you are on better, you probably want to simply leave the DAC off, though. You should be able to do this with devd, but I have not tried it. -- R.
