I have seen this problem also.  We just spent several days trying to
figure out what was wrong.  Originally we thought we had a bad run
of twisted pair, or termination problems.  Then we notice the problem
with just a very short run of phonenet.  And the fact that the LocalTalk
light on the FastPath was not flashing was also interesting.  

Shiva's suggestion of putting a Mac on the network is absurd.  Does this
mean in every cluster of EtherTalked macs with a LW, I need to budget a 
Macintosh to just 'hang out' on the network?  (So the price of networking
a LaserWriter is $1600 (univ price of fastpath) + $1000 for a Mac Plus? )
