That means: If you run "modprobe scanner", automatically use the
options you provided. So you don't need to type them everytime.
However, you still must run "modprobe scanner".

Maybe I'm wrong, but I don't think that will achieve anything. If you
do "rmmod scanner", then run "scanimage -L", that really works?
It doesn't work here.

Usually, there are two approaches to load the scanner driver when
booting:

* Put "scanner" in /etc/modules (works on Debian and Mandrake)
* Add "modprobe scanner" to /etc/rc.d/rc.local or similar (RedHat)

Automatic loading works with the hotplug utilities.
