The problem has been fixed in 2.2-BETA and -current.

"DOS 3.3" really means filesystems compatible with DOS 3.3 rather
than created by DOS 3.3.  These are partitions types 1 (12-bit FAT)
and 4 (16-bit FAT) as well as floppy formats.

Partition type 6 (size exceeding 32MB) filesystems can be mounted
safely if the cluster size does not exceed 16K.  (For 2.2-BETA and
-current, this limitations does not apply.)

The partition types already mentioned work (with loss of long filenames).
More recently introduced types (ie. VFAT32) won't.
