Temps with that kernel are pretty much the same, ~ 39 - 40 C.  AMD
Phenom X6 1075 cpu.  AMD cool & quiet is turned on in BIOS, so it scales
back nicely when not being flogged.

I think I do notice more cpu activity, but can't quantify.

Phoronix has been going on for a while about power regressions in the
3.0 series kernels: e.g.

We don't have any Intel machines running the newer kernels yet.
