Of course, if your monitoring tool uses /sys/devices/system/cpu/... to
get the info, and cpu1/cpufreq is a symlink to cpu0/cpufreq, then
naturally it's going to display the same values for both cores.

On my system (Core 2 Duo as well) the two cores scale independently. Are
you sure you have a Core 2 Duo and not a Core Duo? IIRC the Core Duo
cores do not scale independently.
