    I saw one report where the recent drm security hole fix broke dri
    for one user. Whilst it seems an isolated incident, could this have
    more impact than we first realised ?

    Worse case scenario we can drop out the multi-bridge support for now
    if it needs work. Mike left SGI now, so we'll need to find someone else
    with access to a Prism to make sure it still works correctly on a
    real multi-gart system.
