I have added code to radeonhd to fetch reasonable chip limits from AtomBIOS - as this is scarcely documented, I'm not entirely sure everything is right, though.

So please test latest git master, and check whether the values in the log printed at (II) RADEONHD(0): Power management: Raw Ranges and (II) RADEONHD(0): Power management: Valdiated Ranges look reasonable.

radeonhd decides to use reduced power for off and idle only. I've tested 168750 kHz / 400000 kHz / 1.200 V with two screens, HDMI and Xv - works without any corruptions.
