fdisk (eg, fdisk /dev/ad0) should tell you what slices you have, and
disklabel with appropriate slice argument (eg, disklabel -r
/dev/ad0s1) should tell you what BSD partitions you have on that
slice.  What do those say?  Are you unable to mount the partitions as
reported by disklabel?

You could boot from the DragonFly livecd, which has ee on it, but
that's probably not much help if the above (fdisk, disklabel) didn't
already work.
