You can just use user-mode. The kernel auto configuration uses only the mac address (or md5 privacy hashes) on advertised prefixes. So if you dont need it for booting, just do it afterwards. You find the auto code in: net/ipv6/addrconf.c There is btw a sample for specual z series adapters which need to distinguish multiple partitions on a single hardware card, I guess that might be similiar to what you seek. But why dont you just hardcode the local part or use statefull configuration?
