You don't need to do it via the fstab, because the permissions are
persistent in the filesystem. Just mount the filesystem on /tmp by
hand, then chmod <whatever> /tmp after mounting it and then it will
always have those permissions (wherever it is mounted).
With tmpfs there is no persistent storage to keep the permissions, so
there must be a way to set it from fstab. With msdosfs there is no way
to store the unix-style permissions in the fs, so there must be a way
to set it from fstab. For UFS, the mode is just stored in the fs.
