Even if that would be the case (which is highly unlikely), you should
still be fine. While stateless configuration is indeed based on the MAC
address, it doesn't take the MAC address as is which it would then put
in your IP address; rather, it does some transformation. Which
transformation that exactly is depends on whether or not you use the
privacy extensions, though. If you don't, I believe it simply adds some
"ff:fe" somewhere in the middle of the IP address.
