So unfortunately i didn't have a recent BE, but I was able to do the 
following to get back up:

1. download latest CURRENT snapshot memdisk from ftp.freebsd.org and put 
it on a usb drive
2. boot via usb drive and enter live shell
3. load zfs kmod:
     kldload zfs
4. import zroot:
     zpool import -R /mnt/ zroot
5. mount ROOT filesystem:
     zfs mount zroot/ROOT/default
6. copy usb loader to zroot:
     cp /boot/loader /mnt/boot/loader


i'd recommend just using boot environments, it's much easier and is 
specifically what they are for :)
