The same does happen on my cpu here,
which is an  AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ 

                    |            CPU 1
                    | Idle       713,8%
                    | 1000 MHz   1182,6%
                    | 2,00 GHz    23,9%
                    | 1,80 GHz     9,5%

And the idlestats are empty for the second core 

          Package   |            CPU 0
POLL        0,0%    | POLL        0,0%    0,0 ms
C1         79,6%    | C1         79,5%    2,7 ms

                    |            CPU 1
                    |
                    |
