Ah, yes - tricky.  I think it could be done reasonably tidily by having
fdisk_reread() creating a phoney fdisk_disk struct for the complete
set of md devices and hanging the actual md{0-15} devices off of it
as partitions.  Perhaps you already tried that too ... :-)

However, I'll give up trying to detect md devices for now, or I'll take
much too long to get any code out.

It sure beats jumping to another virtual console and recreating /dev/hd*
with the device major/minor numbers of the devices you really want to use!
