The knfsd-1.4.4 package has a separate nfslock initscript
that attempts to start rpc.statd and a new daemon rpc.lockd.
The script fails with the message
Starting NFS lockd:
lockdsvc: Invalid argument
presumably because the kernel-2.2.5-22 package does not
enable (or possibly even have) this as a separate service.
This is correct, a future release of the kernel rpm will have a patch
that will split lockd in a separate kernel thread that can be fired up
from user space.
I did not have time to get around it yet. :-)
