This is in violation of RFC 4862 Section 5.5.3 Item d, right?

    "If the sum of the prefix length and interface identifier length
     does not equal 128 bits, the Prefix Information option MUST be
     ignored."

Basically, anything besides a /64 on an Ethernet isn't going to work.

Unless I mis-understood the question?
