Binary package hint: xserver-xorg-video-intel

I experience significant performance loss with ubuntu 8.10 alpha 3 with my Intel DG965WH based system and SVDO/ADD2 video card. Actually, the performance loss started with ubuntu 8.04.1; I upgraded to see if there was any performance gain with the new version. While "glxgears" produced values between 1580 fps and 1496 fps with ubuntu 7.04 and 7.10, respectively, now I can only achieve something like 445 fps with ubuntu 8.10 alpha 3. I get an error message when starting glxgears that "TTM" was not available and classic mode would be used. Similary, the flight simulator "flightgear" achieves frames rates of 1-2 fps only.
My suspicion is that some of the hardware acceleration features of the X3100 system are not being used, and I don't know how to activate them with the new xorg.conf structure and the underlying automatic configuration approach.
I would like to see the graphics performance go back to the values achieved in ubuntu 7.04 and 7.10.
Your help / comment is greatly appreciated.
