This is because of the way the CPU chip is designed. I don't have the link handy, but I think it was in a CNET review that I ran across it the first time. The 2 CPUs are on the same chip, and share the same clock and L2 cache. They always run at the same speed, even if the second CPU is not doing anything. Also, you can not put just one CPU to sleep. (Depending on what definition of CPU you use, I guess you could consider it one CPU with 2 cores or processing units...)
