2.6.28 ought to be able to work;
the one caveat is that powertop is reporting more accurate data in
newer kernels (the newer kernels expose more details specifically for
powertop) so it needs to be investigated to make sure this is not just
some cosmetic issue.
(note that C3 might not be the right idea per se with such USB device
in, but that is a different story)
