Macbook Pro with Lion: scrolling via trackpad vs. mouse

Question

So the default scrolling behavior for the trackpad in Lion is to scroll in the direction of your finger movement similar to the iPad. This can be changed in the trackpad preferences by un-checking Scroll Direction: natural. I get that part. My problem is that un-checking or checking this box in the trackpad settings also causes the box in the mouse settings page labeled Move content in the direction of finger movement when scrolling or navigating to be checked or un-checked - effectively tying the mouse scroll wheel behavior to the trackpad scroll behavior. Is this a bug?

I want to be able to scroll with the trackpad in the default Lion way while still being able to scroll with a mouse wheel in a conventional way. Is there a workaround to the above issue to be able to do this?
