comment:
:Enabling floppy - this works in RHEL6, I just replicated the procedure
:1)  mkdir /media/floppy0
:2) create file 
:/etc/sysconfig/modules/floppy.modules 
:with content:
:#!/bin/sh
:
:if [ ! -c /dev/floppy ] ; then
:        exec /sbin/modprobe floppy >/dev/null 2>&1
:fi
:
:3) chmod +x /etc/sysconfig/modules/floppy.modules 
:4) test it: 
:mount -t msdos /dev/fd0 /media/floppy0
:
:5) if all goes well, add to /etc/fstab:
:/dev/fd0 			/media/floppy0 		auto 	rw,noauto,user,sync 	0 0
:
:Check with mount -a before you reboot.
:
:After reboot, it is not possible to mount diskette via Places -> Diskette drive
:
:and this is how this problem has happened.
