You are correct.

I have just tested and verified this on with a brand new core2 quad
9650 3.0GHz here at work.

A bare bones system (ASUS P5Q) with 4GB of corsair DDR2 memory netted
58W total system power at idle as measured by a killawatt meter

After setting cpufreq and advanced C states in the bios this was
reduced the wall power to 46W with or without the acpi-cpufreq driver
