You are right that I am not using devfs and that floppy isn't
mentioned in my /etc/modules.conf. And my /etc/modules.conf is indeed
mostly what my distribution (Debian) has been giving me after running
its update-modules script (I believe it runs automatically at every
boot). However it does get loaded automatically when I am mounting
/dev/fd0. I believe this is similar to that it was loaded automatically
when I cat /dev/fd0.
/tmp# grep floppy /etc/modules.conf
/tmp# lsmod |grep floppy
/tmp# mount -t msdos /dev/fd0 /floppy
/tmp# lsmod |grep floppy
floppy 46428 2 (autoclean)
/tmp#
