Then we teach the bootloaders installer to detect whether all the member
disks are on the same controller, and refuse to install (or atleast warn
at that point) if not.
That being said, I don't know whether grub2 is smart enough yet to probe
all the controllers for disks, not just the ones accessible via int13.
If this is the case then this particular failure mode is reduced to only
being an issue on unsupported controllers.
