My first suggestion would be to try an image with recent stable/9 if you can find
or produce it.

Failing that, you can set vfs.zfs.debug=1 at loader prompt before booting.  That
could shed some light on what is going wrong.  The most likely possibility is that
/boot/zfs/zpool.cache in the boot/root filesystem of the boot/root pool does not
have an entry for the root pool.

Further, I believe that instructions on the Niclas' page won't result in a
bootable pool with 9.0 or 9.1.  With stable/9 they should work.
The problem is that zpool.cache is not populated at all.
You can try to specify cachefile property to zpool create and then copy
zpool.cache to boot/zfs/ on the newly created pool.
