That only works if the dinode structures line up exactly to whatever these

FreeBSD's restore from older releases might work, but only for the 32-bit

FreeBSD deleted some compat code in the kernel some time ago, and it
turns
out that restore used that to read old dump
tapes, so we broke old dump
tapes.
So you can't use FreeBSD's unmodified.
May be run an older release that has this code?
