# echo low > /sys/class/drm/card0/device/power_profile 
"resolves" the issue. Default power management settings for KMS put the card in
high performance mode on AC power.

# echo dynpm > /sys/class/drm/card0/device/power_method
Dynamic frequency scaling may work for you, though the screen flashes when
power levels change. Still seems to run too hot. I'm sticking to low for most
