Even after doing insmod raid and insmod mdraid, the devicesi simply don't show up. grub-install keeps comlaining that 'no mapping exists for' the mdX device.

It's only "documented" in this wishlist bug report:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=492897

We check already the version in the superblock and print out an error if
it's not 0.90.
But the problem is the 3 1.x formats differ in the location of the
superblock.
