Thanks for opening the new bug, Clint.
On my machine portmap is started/running anyhow, also if no nfs share has been mounted ever. In Lucid I have just installed 'nfs-common' (not the kernel server!). It is only used when I temporarely mount some nfs3-exports from guests in VBox, or nfs4-exports from my nas (running Lenny-armel).

You need to install nfs-common also if you only want just the client - and that brings portmap and rpc.statd.
Amaizingly; stopping portmap also stops rpc.statd?

Another observation:
sshd cannot be stopped manually:

# /etc/init.d/ssh stop
 * Stopping OpenBSD Secure Shell server sshd                             [ OK ]

but 'daemon.log' tells me it is restarting immediately (and appears with
new PID in process list):

Feb  1 21:20:20 localhost init: ssh main process (1882) terminated with status 255
Feb  1 21:20:20 localhost init: ssh main process ended, respawning
