Yeah that's just about it - since the native OS doesn't have a virtio-blk-pci driver
then someone would need to write an NDRV similar to the way in which Ben wrote the
QEMU VGA driver. Don't suppose you know anyone with any MacOS 9 development
experience who might be interested?

Glad that you found it useful :)
