Actually, I was unable to disable it for my Magic Mouse, though. According to the release notes: "Multitouch trackpads that only support two-finger gestures will not have an option to reverse the scrolling direction in the Trackpad System Preferences pane." I assume the Magic Mouse only supports two-finger gestures, so maybe that explains it. Either way, I had a really hard time getting used to it. I ended up having to revert to Snow Leopard thanks to issues with Dropbox, Evernote and NewsRack anyway, but I'd be surprised if that scrolling behavior and a lot of the new UI weirdness actually makes it to the final Lion GM. We'll see.
