Why? I have never needed to use fdisk to create solaris partition in order to
create a pool. I simply use
# format < /dev/null
Searching for disks...done
AVAILABLE DISK SELECTIONS:
0. c8t0d0 <DEFAULT cyl 30512 alt 2 hd 255 sec 63>
/p...@0,0/pci1297,5...@7/d...@0,0
1. c8t1d0 <DEFAULT cyl 14590 alt 2 hd 255 sec 63>
/p...@0,0/pci1297,5...@7/d...@1,0
Specify disk (enter its number):
...
to find the disk names, then
# zpool create xxxpool c8t0d0 c8t1d0
(in this case).
This works even if the disk was MBR before.

I'd try 'zpool export' from the OpenSolaris system, then 'zpool import' on the
FreeBSD one; this may fail if the LiveCD system you are using is too new and
the pool created is of a version unsupported by FreeBSD yet.

Probably because of the fdisk step you mentioned.
