Hi Daniel, first thing: We never got to the deepest processor sleep states (C3, C4) when we originally ported coreboot for the GM45 chipset. But we didn't see a difference in power consumption back then on the Roda/RK9.

Anyway, I don't think it makes a big impact, but could you rerun your measurements after `powertop --auto-tune`.
