ZFS Root Won't Mount - Unknown Filesystem

I'm attempting a new install of 9.0-RC3 amd64. My system has 4 500 GB
drives. Using this tutorial as a guide:
I created a boot and a freebsd-zfs partition on each drive. Then I
created a raid1z pool using all 4 drives. I followed the rest of the
tutorial exactly and ensured that I copied the zpool.cache to boot/zfs.
When I try to boot my new system, it all goes fine up until it's time to
mount zfs:zroot. It fails with an "error 2" "unknown filesystem"
error. I don't know if this means anything but at the mountfrom prompt,
the system will not accept any keyboard input. Same keyboard works fine
when booted into LiveCD.
Unfortunately because I can't figure out how to get a LiveCD type
environment with sshd running, I can't copy and paste exact error
messages or command outputs.
I've searched and the two things that seem to be important are that
there's a zpool.cache file and that the zfs partitions are correct. A
'gpart show -l' shows my partitions something close to this:
34 <big number> ada0 GPT (456G)
34 128 1 null (128K)
162 <big number> 2 disk0 (456G)
What have I done wrong and what do I need to do to get my zfs:zroot pool
mounted as root?
