Well, it appears that this actually has something to do with the 9 
Recommended patch cluster. I took another Ultra with a new install of 
Sol 9, and it worked fine as an NFS client. After installing the patch 
cluster, it no longer works as an NFS client to the Linux box.

It would appear that the fault is in the Linux box, probably, unless a 
recent patch cluster contains an NFS bug.  I was going to back out the 
NFS patches from my Ultra 2, but even though the install script for the 
patch cluster swears that patchadd is run with the -save option, the 
patches cannot be backed out. I figure it is not an NFS patch now, 
anyway, since the application of the three NFS patches in the cluster to 
a fresh Sol 9 install does not break the NFS client to Linux server.

Any other thoughts before I find some workaround like not patching my 
workstation?
