If you have seen the flight simulator that's been in Google Earth for awhile now, but didn't like using keyboard commands, and happen to have a Playstation 3 controller...good news, the sticks on the PS3 controller work well with the flight simulator. Still have to use a mouse to start it and stop it though.
I'm using Ubuntu 9.10 64bit, and I just plugged the PS3 controller into my computer with it's USB cable and it worked right away.
So, give it a try
