Hidden in the Developer Tools package, there is a System Preferences panel that serves the same purpose as this hint about the CPU Palette. After installing Xcode, navigate to /Developer » Extras » PreferencePanes, and then double-click on Processor.prefPane to install it. The Processor panel will add itself in the Hardware (not Other) section within System Preferences. Using this panel, you can do everything you can do with the CPU Palette, minus the graphs but plus some L2 Cache and frontside bus info. The best part, however, is the fact that you can use the panel to add a menu bar item that replaces CPU Palette. From the menu bar icon, you'll have access to the preference pane, the option to use two or one cores, and the CPU Palette itself.
