I've always wondered why pseudo-devices don't attach to a "pseudo" bus,
one that has no hardware behind it and exists solely for pseudo-devices
to attach to. That's what I did when I wanted to build a particular
flavour of pseudo-disk and discovered I needed it to have a struct
device for internal purposes.
