IPv6 over atm

Has anyone done any work on v6 over atm?
I'm wondering how the link layer address is fomulated on cisco.
When i do a "show int atm2/0.x, i can see a link layer address which has been inherited from another interface of the router.
This inherited link-layer address is used to create the link-local address.

During neighbor discovery i expected to the the same link layer address being exchanged in the address option of the NS/ND.Instead i saw an obscure link-layer address.Testing across different setups the link-layer address changed each time,so i know its not a fixed address.
Anyone know how the link-layer address comes about on an atm interface?
Networking, sometimes i love it, mostly i hate it.Its all about the $$$$
