What worked for me on Jaunty with 9.8 ATI driver. Go to Catalyst Control Centre a select Always On for Vertical sync in 3D/Preferences section. However, when I first tried this the X server froze. Then I updated (flashed) the motherboard BIOS (Asus M3A78-EM) to the newest revision and the freezing problem (and tearing) was gone.
