When did you inspect the debug files? One effect I can imagine is that if your system was previously stuck at RPn and never upclocking the GPU when X starts. The question would then be what is preventing the GPU from reaching its lowest power state again.

After I logged into an xfce4 session and powertop showed idle had been reached.

So it looks like rc6 is functioning as the GPU is downclocked whilst idle and the rc6 residency counter is increasing. I guess we need a new tree to bark at. -Chris
