    Subject[PATCH] sis drm module (revised)
    Hi,

    without this patch, only root can execute DRI applications under X.
    Users can't and just receive a (incorrect) "out of video memory" error,
    which is basically a "permission denied".

    The revised version of this patch also makes newer DRI applications
    (such as "Soldier of Furtune") run.

    Please apply. Now for real! :)

    Thomas

    PS: The file to be patched is located in drivers/char/drm/ in the kernel
    tree.
