If you really want to do some detective work you could dump the whole MMIO space and compare differences. You should be able to find definitions for many of the reg offsets in the docs at intellinuxgraphics.org, maybe there's something we don't dump that's changing and that explains your power consumption changes. -- Jesse Barnes, Intel Open Source Technology Center
