Apple Mouse Accelleration

On an iMac, with a wireless mouse and keyboard, is there anyway to diable the accelleration “feature” on the mouse (my Dell at work has a control panel switch that adjusts the accelleration). The Apple mouse is annoying the way it slows the movement of the cursor based on the speed you’re moving the mouse. Instead of making it easier to use, it just makes it way more imprecise and annoying! The control panel has switches for “speed” (which I have set at the max), and “click speed”, but nothing for accelleration.
