FreeBSD 9.0-STABLE #0 r233503: Mon Mar 26 23:53:01 EEST 2012
In Kernel config file, options:
options         NFSCLIENT               # Network Filesystem Client
#options        NFSSERVER               # Network Filesystem Server
#options        NFSLOCKD                # Network Lock Manager
options         NFS_ROOT                # NFS usable as /, requires NFSCLIENT
buildkernel with these settings results in a kernel which CANNOT KLDLOAD nfsd, and result in error message: "Version Mismatch" or "Exec Format Error"

Commenting out NFSCLIENT results in a kernel which is able to load and start nfsd, while the PXE terminal client is still able to boot and mount root from NFS (provided nfscl_enable="YES" is specified in the /boot/loader.conf of PXE's root). so NFS_ROOT does not necessarily require NFSCLIENT, but NFSCLIENT certainly seems to require NFSSERVER.

Comment out NFSCLIENT
