Hi, I haven't followed this thread but this sounds like similar to the problem I had with USB printers. I had several and turning them randomly on made them have different ulptX device. I made a script for hotplug that creates symlink that points to the right device node. So, if you modify my script and use disklabel and labels beforehand, maybe it will help you.
See for more details: http://users.openbsd.fi/iku/opensource/hotplug-1.1.tar.gz
