I suspect there is some lingering effect from the previously formatted
partitions.  The kernel (or the mount command) is apparently having
trouble auto-detecting the filesystem on the partition.  I can't say
exactly why without crawling through the code, but things to look at
would be the MBR of your drive (specifically the partition entries) and
the first couple of sectors of the partitions themselves (grab the
sectors with dd and use your favorite hex editor to examine them).

You might also test what happens if you try to mount the third partition
as MSDOS.  I realize this is incorrect, but I seem to recall something
about filesystems being tried in order until one of them works (ie: it
could be for some reason the third partition won't mount as msdos so it
is properly mounted as ext2, while the first two may appear for whatever
reason to be valid msdos filesystems, which is likely tried first since
it's probably compiled into your kernel while ext2 is probably a module
loaded at runtime).  I know this is how the old init scripts worked, but
I don't know if the busybox mount currently works this way or not...

NOTE:  I personally recommend you use the -t switch, or put the entries
for all three partitions into fstab.  I tend to not trust auto-detection
mechanisms, particularly on systems stripped as small as LEAF.
