As far as I can see in the latest addressing draft, there is no requirement that the EUI-64 be derived from the MAC address of the particular ethernet card in question. RFC 2464 only mentions the use of MAC address in regards to stateless autoconfiguration. The EUI-64 could be formed manually, by setting the Universal/Local bit to Local and then filling in the rest of the ID with anything. This is totally unrelated to the MAC address.
