In case anyone still cares, and if a VM running in Parallels on an OS X box 
is a good enough test for people...

Matthew's answer tested out as being correct.  The VM booted correctly 
after the binary update, but failed after upgrading the version of the 
zpool.  Notably, `zpool upgrade -a` mentioned this in it's output, and gave 
the command to fix the problem.  (Which would update the bootloader.)
