All:

Got some good news when I spoke to the FAA today. Based apparently on
the letter from my primary physician that the ADD diagnosis did not
exist in 1965, and noting my educational, professional, and flight
training history, the FAA has reinstated my medical. They said they'd
send out the certificate this week or next, given the holiday.

I'm still upset at the AME, who pulled the trigger on this based on
almost zero facts and did not offer any guidance in getting a
determination of whether I was really qualified to fly. However, I
have to hand it to the FAA for making a relatively quick determination
based on the additional information -- I think they deserve credit for
that.

Thanks, everyone, for the supportive comments.
