By using radeontool, I have been able to fix tha problem. Backlight goes off and on fine. I also want to tie radeontool to Fn+F4, but have not done so at this time. I have set hw.pci.do_power_nodriver to 3, its most aggressive setting, and have not seen any problems of this point. Since I just changed this yesterday, I can't say it's well tested, though. At this point, all appears to be pretty well. I do need to test whether the USB is off and I THINK that there is a way to get a log of power state information when suspended, but I an not sure what it is. Senior moment, I guess. -- R.
