Sorry if I wasn't clear. Most all of the data is readable and complete
if I mount the filesystem read-only. It just panics the box when mounted
read/write, and fsck can't fix the damage.
My question was more along the lines of whether or not dump/restore
would see that those corrupted directory and file inodes were indeed
corrupt and not bother attempting to back them up, or if it would
happily back them up and restore them in their corrupted state to a new
filesystem, thus trashing it.
If it does, I can always use rsync.

Ironically, this is the machine that holds the backups.
