You can use zfs.root.mountfrom="zfs:data/root" in /boot/loader.conf 
instead of an fstab entry.  Mountpoint=legacy is required either way.

This only applies to Solaris, IIRC.

I ran into that problem as well.  The instructions for root-on-zfs for 
9.x (at least as of 9.1) are wrong--you need to use the 8.x-style 
instructions with mountpoint=legacy for / and, for fresh installs, 
leaving the pool imported and copying over /boot/zfs/zpool.cache.
