Can you run that while doing devkit-disks --mount and attach /tmp/gvfs.log?
So it seems that there are zero uevents when trying to mount the device, which explains why the changed udev rule didn't gain anything. Does it work if you keep the changed udev rule, and do
* insert the floppy
* sudo udevadm trigger --action=change --sysname-match=fd0
After that, devkit-disks --dump should have a file system info, and GNOME should be able to mount it. Does that work?
Sorry, I meant
gvfs-mount -oi >/tmp/gvfs.log 2>&1
