Well, there are some unresolved issues when it comes to CPU-scaling. I did some complex testing on scaling behaviour and it is kinda odd how the performance management enables or disables available cores. On a sense ROM, Riptide-GP tends to have some framerate-issues, because only 2-3 cores are active from time to time. And it only clocks around 1 GHz most of the time. Enforcing all cores @1.4 GHz smoothens everything out, but nVidia/HTC really need to work on their modules! Can't really tell how our kernel devs can affect scaling behaviour, because there surely are some propritiary blobs which nVidia won't open up..
