No, they are *different* IDs. The Linux NFS server's fsid is for export 
purpose (used to construct NFS file handler). It has *nothing* to do 
with "st_dev" obtained from "stat" system call (that is used by Linux 
VFS layer).

To display the linux (nfs) server fsid on client, the easiest way (I 
think) is probably using some network protocol analyzers that know how 
to interpret Linux server's file handler (did you try "ethereal" yet ?). 
If you decode the server's file handler, the fsid you're look for should 
be there.
