howto enable NFSv3 in 2.4 kernel

hi,

i've got a 2.4.31 kernel with NFSv3 support (built as a module) and NFS works but it does not appear to support version 3. i can verify this as "rpcinfo -p grep nfs" reports that there is only v2 support.

100003 2 udp 2049 nfs 100003 2 tcp 2049 nfs

indeed, when trying to mount a NFS share from a remote (fedora 2) client, capable of using NFSv2-v3, i have to explicitly use "vers=2" in the mount such:

mount -t nfs -o vers=2,rw,soft,intr 192.168.0.8:-export-datamnt

without the vers=2, mount complains that the server is not available:

mount to NFS server '192.168.0.8' failed: server is down.

even though the server box is running fine.

what do i need to do (parameter to nfsd kernal module?) to enable the NFSv3 protocol?

thanks -ray

below is the relevant network fs section of my .config for the 2.4 build
