Wireshark-dev: [Wireshark-dev] Funky packet, bad capture, bad display or what?

A friend sent me a trace with this packet:
Frame 1 (78 bytes on wire, 78 bytes captured)
    Arrival Time: Jul  9, 2006 13:58:01.527266000
    Time delta from previous packet: 0.000000000 seconds
    Time since reference or first frame: 0.000000000 seconds
    Frame Number: 1
    Packet Length: 78 bytes
    Capture Length: 78 bytes
Ethernet II, Src: 00:00:80:11:ea:96, Dst: 45:00:00:4e:91:fd
    Destination: 45:00:00:4e:91:fd (45:00:00:4e:91:fd)
    Source: 00:00:80:11:ea:96 (CrayComm_11:ea:96)

First, the hex does not seem to match with the EthernetII decode. Second there were three of these in a row with incrementing MAC addresses. I am not sure what I am seeing, (and neither is Ethereal). My Ethereal decodes other frames correctly. Is it possible his capture is confused or what? Any ideas? (I do not know what version he has, but he said he downloaded it in the last few months.)
