Hi Bonzi.

I can't find any mistake in your instructions. Just a minor addition I would like to make: You don't need to format all "linux" type partitions, just the music partition, all others are formated by the upgrade process (i.e. application of a .upgrade file) or actually: simply overwritten completely by an ext2 formated partition image.
The /dev/hda2 and /dev/hdb2 partitions are currently not used at all, at least not by the original software.
