Than I would assume that there is a bug in your new implementation. RFC3146 section 8 states that the link layer option is of length 3. In addition, my proof of concept implementation also worked with MacOS X and I double checked the ndisc packets directly on the firewire line using a firewire sniffing device (firespy).
