I assume it is actually a tmpfs rather than a regular filesystem on a
true ramdisk ? (what does 'cat /proc/mounts' show?)

A tmpfs doesn't have a stable identifier (like a device number) to use
to identify the filesystem.  You need to give it one.
Try adding
   fsid=27
to the export options for the problematic filesystem. e.g.

/ramdisk/home/knoppix   knoppix(sync,rw,no_root_squash,fsid=27)
