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/data /mnt

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

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

# Network File Systems
#
# CONFIG_CODA_FS is not set
# CONFIG_INTERMEZZO_FS is not set
CONFIG_NFS_FS=m
CONFIG_NFS_V3=y
# CONFIG_NFS_DIRECTIO is not set
# CONFIG_ROOT_NFS is not set
CONFIG_NFSD=m
CONFIG_NFSD_V3=y
# CONFIG_NFSD_TCP is not set
CONFIG_SUNRPC=m
CONFIG_LOCKD=m
CONFIG_LOCKD_V4=y

one thing to add -- the client box is able to mount other NFSv3 shares
on different servers so it is a genuine issue with getting NFSv3
enabled on the server side.
