Just as a data point, I am exporting a zvol via iscsi on 9.2 with 
iscsi-target without any other issue than that iscsi-target occasionally 
crashes (very rarely) and I have to start it again to have my volume 
re-appear.

# extent        file or device          start           length
extent0         /dev/zvol/rdsk/internal1/photos 0       500GB

Note that my kernel's zvol.c is patched, but I think that was all for 
using (a clone of) the volume locally with ccd to mount the filesystem 
on it for backups and it should not be necessary.
