I managed to patch the 2.6.35 kernel so that I can undervolt the CPU and compare in equal conditons the new power saving features. It seems to be working, or at least the fan doesn't start very often. However, I'm confused for I don't see any performance difference between the 'high' and 'low' profiles. I tested OpenArena and a molecular viewer. The latter can also display the frame rate and nothing seems to change between both profiles. Isn't this odd?
