    agp: Handle multiple devices more gracefully

    Currently agp(4) effectively assumes that only one driver instance
    exists, as the generic attach routine attempts to create /dev/agpgart
    and triggers a panic if it already exists.  Instead, handle this
    situation by creating /dev/agpgart<unit> and making /dev/agpgart an
    alias of /dev/agpgart0 for compatibility.
