You might also try forcing NFSv4 on the Ubuntu system.
Which raises the other question I have about the export map from the server above. I thought that NFSv4 export tree was based on a single root, "/", and everthing else was subordinate to that. So how would one go about merging the file systems exported above as NFSv4 export tree? Anyone? The other problem, of course, is that Bill would need the ubuntu autofs5 package to use NFSv4 in this way and it probably still has the 5.0.3 bug you reported (and we fixed) so ubuntu would need to add the patch to fix that. And the mount tree would be a little different to what is described above too.
