2.6.34 Merge window, part 2

Thanks for the clarification - hopefully this will lead to extremely low idle power consumption for general purpose graphics cards within a few years' time. This is important to me as the idle power consumption is a major factor in the decision of what hardware to buy - much more than its peak power consumption given that 99% of the time I'm not pushing the card to its limit, but still need that limit to be high for the other 1%.
