No. The number in that column is a reference count. Modules that are not
marked 'autoclean' would never be removed automatically. Modules that
/are/ marked 'autoclean' *and* that have a reference count of zero would

Maybe. It depends on the kernel requesting the relevant modules at the
right time. In the case of the masqerading modules, I don't _think_
there is a way to autoload them.

Does the memory use really bother you that much? It's generally less
than 200k, maximum, on any machine I ever saw....
Anyway, if you *really* want to have automatic unloading of modules, you
could run 'modprobe -r' or 'rmmod -a' in a cron job. Do that as root
and it should automatically prune modules for you.
 I have modutils from unstable installed; this may or may not work
