FreeBSD 10 w/ fresh root-on-ZFS fails to boot

Passes short, testing long.

I doubt it's the disk, as the Guided install (UFS) consistently works with
a partition table on the same sectors. I reinstalled it after the ZFS
trials and before writing the email, just to be sure). I booted into
whatever was on there before (9.1 maybe?) prior to putting 10 from the
guided install on, so that also worked.
