I have the same problem. I can format a new stiffy from within Terminal (gfloppy) but cannot access it from "Places"/"floppy drive". When I use the following command (sudo mount /dev/fd0 -t auto /media/floppy) inside Terminal the floppy will mount and it is now possible to use it but appears as "floppy0" under "Places" and on the desktop.
