Look like not rmmod but the kernel decides which modules should be
unloaded. The code is in sys_delete_module() in kernel/module.c.
Here is the condition 2.0.36 uses to tests if a module should be
unloaded:
	((mp->ref == NULL) && (mp->state == MOD_RUNNING) &&
	((GET_USE_COUNT(mp) & ~MOD_VISITED) == MOD_AUTOCLEAN))
Current 2.1 kernel uses a somewhat different test but the effect is the
same.

If nobody complains really fast I'll give modutils a crontab in the next
package.
