Ah, I have found several references that back-up these standards - ahem, 
however...I failed to mention (because I didn't think it was an issue)
that I was attempting to route over Token Ring, which uses FUNCTIONAL
Addresses rather than multicast.

I found references to the addresses in:

1988 NIST agreement (which reversed IS and ES addresses)
AT&T documentation (the addresses for csma come from their bank of numbers)
TOP/NetBIOS Working Group of the MAP/TOP committee

Basically, 'cisco' made a boo-boo in several ways:
1) all standards related to these addresses state that they must be
   CONFIGURABLE (PROMS do *not* count!)
2) in some cases, the 4th and 5th octets were reversed - in others it is
   inexplicable where they got the numbers.....

A fix is on the way (OH, how I wish I didn't have to deal with TR!).
