    Keep in mind that setting nvidiafb to totally ignore the EDID (either
    by not compiling in EDID support or by using e.g. the ignoreedid patch
    I had proposed) the snow effect is extremely reduced, to the point of
    being barely perceptible during normal usage (not as clean as X, but
    still very good).

    Also, I'm wondering if it might be worth looking at the progress done
    in nouveau, and the drm stuff they've implemented (or at least the new
    memory management and maybe some of the 2D stuff).
