Maybe not a loop device? But how about handling this at partition scan
time then? Partitions are after all nothing else then devices
with remapped sectors in first place. Could you manage to insert
at the proper place in paritions/*.c the magical + 1.
It could then be turned in no instant in to a global kernel
option - whch it what it is after all.
