"mei_device" works the best for me.  Tomas, what you think of as a "MEI
Device" really is a "MEI Controller", it bridges the difference between
the PCI bus and your new MEI bus, so you will need to start thinking of
these things a bit differently now that you have created your own little
virtual bus.
