show ..") and I can import the zpool ("zpool import zroot"), and
see all my data. I just can't seem to boot from it. I tried rerunning
the "gpart bootcode" commands on both drives (no errors), but no
effect.

Maybe the machine is just too picky about partitioning scheme? Try this
black magic:
printf '\ny\n\n\n\ny\n\ny\n\n\n\n\ny\n' | fdisk -u ${YourDiskName}
