I am not sure if this will help your problem but...
If you recall from the AUX 2.0 README disk, there is some mention of a 
machine that will server to hold updates for AUX.  As a matter of fact, the
machine does exist and does have a fix for AUX 2.0 and ddp. 

aux.support.apple.com:~ftp/aux.patches/supported/2.0/ddp/*

This is the README file from the update.

Date of Change:
07/18/90
Responsible Person/Organization:
Apple Computer, A/UX Engineering

Program Name:
/etc/install.d/boot.d/ddp

Reason for Change:
The ddp driver in the A/UX kernel would not recognize AppleTalk networks
with low network numbers.  This would show up as missing zones in the 
chooser.

Description of Change:
No description.

Notes:
The INSTALL script will install the new ddp driver and update your kernel
for you.
