[You probably figured this out, already, Bob... but this is what I
understand of the problem.]

I've noticed this as well.  FastPath Manager doesn't use DDP longs on
EtherTalk (like most applications). It uses DDP shorts with type "K"
(0x4B, I think). In _Inside AppleTalk_, the authors discouraged the use
of DDP short-headers on EtherTalk, but Kinetics/Excelan/Novell and FPM
predated that standard (I think). 
	 Since DDP short-header packets are removed from EtherTalk Phase 2
(there's no support for them in the AppleTalk driver, I suppose), it
wasn't suprising to me that FPM didn't work.  Getting it to work would
require a lot of work, both on the gateway and on FPM, from what I
understand.

Hope this helps a bit,
