Why is that a problem? You can assemble a MD using whole disks instead
of partition. A block device is a block device is a block device.

Use a volume manager (LVM1, LVM2, EVMS2 ...) on top of the md. Works
just fine.

Autodiscovery is a problem, but I'd prefer to do that in the initrd from
within userspace. That's much cleaner.
