Not true. In fact, Microsoft used to use 1680 density for its install 
disks. I've no idea if it was ever used for Macs, though. In any case, 
it mounts fine on core 3 with -t vfat.

The example i posted above was to show that the disk was not 
automagically detected by udev as 1680. That is what i would expect to 
see on my core 3 box if i used /dev/fd0 (because it's the wrong density).

core 3:
[root at poseidon ~]# mount -t vfat /dev/fd0u1680 /media/floppy/

works fine.

core 4:
[root at apollo ~]# mount -t vfat /dev/fd0u1680 /media/floppy/
mount: special device /dev/fd0u1680 does not exist
