I am using floppies on rare occasions on an old Dell.

My setup is as follows:

/etc/fstab   does not have any reference to /dev/fd0

in the /usr/local/etc/sudoers  file I have the following:

# User privilege specification
root    ALL=(ALL) ALL
aj      ALL=/sbin/umount,/sbin/mount_msdosfs
# end of sudoers file


I have a directory with file permission 755  aj:aj

/usr/home/aj/floppy

( make sure all your users have a directory call floppy
  with the correct file permission )

I use a small script owned by root but may be executed by all

inside this script is a small message tell you it will be
mounting a floppy and it must not be copy-protected

next is the following line:

sudo mount_msdosfs /dev/fd0 ~/floppy

Now I use fluxbox...but this can be adapted to KDE

withing the fluxbox menu I added the following:

aterm -fg white -bg black -e name_of_script.sh

( note: I am using aterm not xterm...but should work 
  xterm -e name_of_script.sh )


make another script to unmount with the following command

sudo umount /dev/fd0

Have fun with FreeBSD...
