Note that ZFS v14 was imported to FreeBSD 8-stable in mid-January.
I can't comment whether it would be able to recover your data.

This is almost certainly the problem.  ad6s1 may be the same as c5d0p1
but OpenSolaris isn't going to understand the FreeBSD partition label
on that slice.  All I can suggest is to (temporarily) change the disk
slicing so that there is a fdisk slice that matches ad6s1d.
