    Do we really want this?

    In my oppinion we run the risk here of encouraging behaviour akin to
    what NVidia is doing - release a small kernel "glue" module and then
    keep the driver proper in a binary blob (in userspace, but still a
    binary blob).
    If the company goes out of business and take their driver source with
    them then users are left with a useless, un-debugable, un-maintainable
    binary blob.
    Don't we instead want to encourage/pressure people to release specs
    and/or source code for their hardware/drivers so open, modifiable
    drivers can be written?

    This opens the door for people to start writing closed drivers. In the
    long run that seems to me like a bad deal for our users.
