VERY interesting! The second link seems to imply that Phoronix has
independently found this same bug that we've been talking about in my
originally-linked ubuntuforums discussion. Specifically, the
interesting quote is:

"Besides the new Linux 3.1 kernel power regression, there's also a
power regression introduced in the Linux 3.0 kernel that has
previously not been talked about on Phoronix. The Linux 3.0 power draw
is up by 24% over the Linux 2.6.39 kernel."


sounds like good news; a 24% regression is MUCH easier to bisect than a 0.05% regression ;-)
