Ah wait a sec - according to the IEEE-1275 spec, the device chosen from
boot-device is the first one that can be successfully opened, i.e.
returns a valid ihandle with open-dev. Since the cdrom device is first
in the list (and can always be successfully opened), it will never try
the next option.
So what you need to do is swap the order over from "cdrom cdrom:d" to
"cdrom:d cdrom" which should give the desired behaviour.
