(Get the code!)
Same issue with the linked 3.5 kernel. Power consumption stays at an higher level after resume. I could not test if running
sudo bash -c "echo ON > /sys/kernel/
sudo bash -c "echo OFF > /sys/kernel/
Brings the power level down the screen locks up when the ON command is issued.
My current guess, although I'm not an ACPI expert, is that the video card at resume time is powered instead of being in D3cold state.
