To clarify, the number "59.7" FPS is not just a random number. It's probably the refresh rate of your monitor, indicating that glxgears (or the radeon driver) is indeed ignoring vblank_mode=0. Most people want a frame rate of about 60, because they want sync-to-vblank support ON to avoid screen tearing :)
