Arne H. Juul had suggested that I check the exports permissions to make
sure root had permission.  He also suggested that I use tcpdump to watch
the network transactions between the server and the client.

In doing that it looks like it finds sbin then init and finds that
then it looks for oinit (which it does not find) and init.bak (which
it does not find).  It seems that the kernel does not like the init
it is getting.  

I made a point of setting EXEC_AOUT to make sure I would not have
problems which had been warned about.  I assume the kernel it is using
is the one on the boot floppy rather than the one on the NFS root

I'm rebuilding the kernel to make _VERY_ sure that EXEC_AOUT is on
and then I'll make sure that kernel is on both the floppy and the NFS
root partition (though it does not seem it would need to be present except
for things like ps).

Thanks to both Arny and der Mouse for their suggestions and insightes.
