It's a kernel-side NFS server, designed for better performance than the
userspace one. As such, you won't find a knfsd binaryon your filesystem.

Confirmed, confirmed, she is a witch!!
Well, actually, no, it doesn't confirm anything. :(
If you are back on the stable kernels, then I suppose you will not be
running a knfsd anymore, if you were at the time.

OK, so the answer almost certainly lies in one of those things you
upgraded. Do you remember what those were? Are you certain you didn't
upgrade something but not upgrade a dependency it might have had?
If you install from .tgz you can never be sure. In fact, at times the
RPMs for 2.1 support have been a bit dicey, but I don't believe there've
been any problems that recently.
Do you recall whether NFS worked while you were running 2.1.126?

Well, everyone is expecting a December release, so if you are having
problems with the 2.1 series, you _really_ need to sort them out as soon
as you can, before the problems become "stable".
Did you have stability problems, speed problems, or reduced capabilities?
For the first two, it is very important that the kernel guys get
the bug report before 2.2 arrives.
For the latter, you will probably find your troubles stem from an
out-of-sync userspace.
