I was testing this on a 2010 vintage HP G71 laptop which has no BIOS 
settings for USB.  I didn't think about it being a BIOS issue since it 
boots gptboot/UFS with no problem.  So I tried booting the very same 
gptzfsboot/ZFS USB drive on a different machine and it boots fine, so I 
guess it is just a HP BIOS problem.  Sorry for the false alarm.
