    Good pointer.

    Looking at the design documents I see mention of what I am saying.
    These are not simple frame buffers with common processors
    glued to them. The design of dri shows awareness of this task
    and associated issues.

    What I am failing to communicate is that there is a fun set of issues
    associated with the use of asymmetric special purpose co-processor
    subsystems for acceleration of any type.

    Of interest dri does work on FC2 (nv driver) with my nVidia
    Corporation NV11 [GeForce2 MX/MX 400] card, glxgears and more. Just
    not as fast as the accelerated driver.
