OK, my computer has 2.6.39-bpo.2-amd64 and I also see this on
powertop's idle stats:

          Package   |             Core    |             CPU 0               CPU 1
POLL        0.1%    | POLL        0.1%    | POLL        0.0%    0.2 ms      0.1%    5.1 ms

                    | C2         99.4%    | C2         99.1%   60.9 ms     99.6%   59.7 ms

Please note that I use powertop 1.97. Could you please let me know
which version of powertop you use?

Thanks.
