    Too many things trying to use AGP... looks like you already
    have agpgart loaded, but fglrx is trying to use its own
    internal agp handling.

    So, either switch off the ATI internal AGP handling, and let
    the kernel's agp management do it (I found this worked
    better for me):

    Section "Device"
    .
    .
    .
      Option "UseInternalAGPGART" "no"
    .
    .
    .
    EndSection

    ... or do the reverse: switch off the kernel's AGP handling
    and let fglrx do it.

    Hmm. That should be fine, assuming that nvidia_agp
    corresponds to your motherboard chipset (which I assume is
    some sort of nForce).

    Hmm, should just be a question of using the kernel's AGP
    handling, by switching off fglrx's internal handling.

    It's certainly worth getting it working for the performance
    boost, and so far (touch wood) I've had no stability
    problems.

    HTH,
