The default NFS implementation did not change between 9.0 and 9.1.
Per the 9.0 release notes, you can change your kernel configuration to 
control which implementation is used -- NFSCL/NFSD are the "new" versions, 
and NFSCLIENT/NFSSERVER are the old ones.  Are you running GENERIC or a 
custom configuration?
