Mine works thusly. I've got the following mount points:
/dev/hda1 on / type ext2 (rw)
/dev/hda6 on /home type ext2 (rw)
/dev/hda2 on /usr type ext2 (rw)
/dev/hda5 on /var type ext2 (rw)
In /etc/exports, one of my shares is:
/ reliant(rw,no_root_squash) excelsior
Now, locally, I do an ls:
[root@ds9 /root]# ls /usr
X11R6/ doc/ i386-redhat-linux/ info/ local/ reliant/
src/
bin/ etc/ i486-linux-libc5/ lib/ lost+found/ sbin/
tmp@
dict/ games/ include/ libexec/ man/ share/
>From reliant, I mount the ds9:/ export and do an ls of the
<mountpoint>/usr directory:
Connection to ds9 closed.
me2v:reliant me2v$ su -c 'mount ds9:/ /mnt/ds9'
Password:
me2v:reliant me2v$ ls /mnt/ds9/usr
me2v:reliant me2v$
Now, the kernel was configured with the following Network File System
options:
#
# Network File Systems
#
# CONFIG_CODA_FS is not set
CONFIG_NFS_FS=y
CONFIG_NFSD=y
CONFIG_NFSD_SUN=y
CONFIG_SUNRPC=y
CONFIG_LOCKD=y
CONFIG_SMB_FS=y
# CONFIG_NCP_FS is not set
Plainly, the CONFIG_NFSD_SUN does something other than what the
Configure.help says it does. I'm not sure what, but it *doesn't* allow
submounts to be viewed as part of the total exported filesystem; only
the physical partition is exported, and not any of the other partitions
mounted on the exported partition (I know, we export directories, by for
clarity's sake...)

Yes, definitely sub-optimal. However, also, definitely something to
drool over... ;)
