I am compiling 2.6.33.3 right now and will soon reboot into it. Leak is still present in 2.6.33.3 - the more GUI activity the more it leaks. So the ~512 objects per second was with xosview running, but moving windows or browsing through menus can leak a lot more (per second). Is version of userspace drm library interesting? It is 2.4.20 (libdrm-2.4.20-12.1.x86_64). Tvrtko Sophos Plc, The Pentagon, Abingdon Science Park, Abingdon, OX14 3YP, United Kingdom. Company Reg No 2096520. VAT Reg No GB 348 3873 20.
