If you want that and good performance too write a virtio driver, and use
virtio disk instead of IDE or SCSI.
I don't think the IDE implementation in qemu supports more than four
disks, that's an IDE limitation. No doubt it could be worked around by
adding more IDE controllers, it's probably not a lot of code but quite
tricky.
