The received snapshot of your BE retains that information
so you shouldn't have many problem so long as its just
rpool spindle failures.

1. Reinstall OS from installation media.
2. Boot
3. # zfs create rpool/restore
4. # zfs receive -vF -d rpool/restore < rpool-snapshot.zfs
5. # zfs rename rpool/restore/ROOT/mybe rpool/ROOT/mybe
6. zfs rename any other filesystems or vols you want to retain
from your rpool-snapshot
7. munge /rpool/boot/grub/menu.lst with rpool/restore/boot/grub/menu.lst
8. # beadm activate mybe

My WAG is things fail when NICs or other devices are missing
on your restored hardware but I can't test right now to see
how badly.
