I would use modprobe -r instead of rmmod. It will remove the modules
loaded because of the module you are removing, unless they are used
by something else as well. You might find a script like this useful:
(untested)
#!/bin.bash
temp1=/tmp/lsmod1.$$
temp2=/tmp/lsmod2.$$
lsmod > $temp1
modprobe -r <module>
lsmod > $temp2
diff $temp1 $temp2 | less
rm $temp1 $temp2
The rm step is optional - if you think you will want to use the
files again, remove it. You do not really need to use lsmod1.$$ and
lsmod2.$$ - you could just use lsmod.$$, but if you want to look at
the files by hand, it helps to keep them straight.
