I tried the CPUFriend posted by @zanzy, as it matches my CPU. The CPU package power at idle, as reported by Intel Power Gadget, is the same, at about 1.5W, for me. This is measured with the display sleeping, which gives me the lowest reading, naturally.
I lost only a very slight amount in Geekbench score, but still, it appears that, yes, it's true there aren't power savings to be had from lower clocks, past a certain point. Perhaps it's not universally the case- I don't know. I only have 2 cores, and some of you have 4, which is a pretty big difference.
Anyway, this testing led me to the discovery that, for this machine at least, the "pmset -b displaysleep" setting isn't persisting. It resets to 10 minutes after every reboot. I'd like to find a fix for this! Though I guess I could just kluge it with a startup script.
