Uhm.... something similar would be needed to handle some Amiga ZBUS graphics
boards more cleanly. 

We know we see the logical boards next to each other... do we have to set some
state in (say) the register softc, exit without starting the board, then, when
the memory shows up, look for an unclaimed register "board" (or vice versa)?

I guess there is no method to attach a device instance two (or
more) parent devices at the same time, right?
