    I have a Voodoo3 2000 PCI card, but when I activate DRM without AGP,

    # CONFIG_AGP is not set
    CONFIG_DRM=y
    CONFIG_DRM_TDFX=y

    the linker complains about an undefined reference to agp_enable. The
    following patch works for me, but I don't know if it is the correct
    solution. (Even if it is, other drm drivers probably need similar
    patches.)

    This problem does not exist in 2.4.0-test8.

    Here is the patch:
