    You need to ensure that the correct modules agp for your motherboard is loaded
    as well as agpgart, and the module for your video card.

    For instance I have

    agpgart
    sis-agp
    radeon

    in my /etc/modules.

    Look closely at /var/log/Xfree86.log to see what it says about not loading
    DRI.
