Ah-ha! That certainly looks like the same issue Miles - well spotted! As it happens, the "zdb" command failed with "out of memory -- generating core dump" whereas all four dd's completed successfully.
I'm downloading snv96 right now - I'll install in the morning and post my results both here, and in the thread you mention. If this works, I may stay with OpenSolaris again - I've been unable to use Nexenta as an iSCSI target for ESXi 3.5 because of the b85 kernel, so this upgrade to b96 may kill two birds with one stone.
