I saw the following issue that may be related (Ubuntu 9.10 Karmic 64bit 2.6.31-18-generic #55) using radeon KMS. Graphics card: RV516 [Radeon X1300/X1550 Series]. Symptoms was very choppy UI and that all swap space was consumed over approx 10 minutes. This happened just after system boot. Compiz and flashy effects are enabled.
