If you have another system, you can try to install new disk into this
system, prepare slices, partitions and make new blank filesystems.
Make it bootable.
Then, using restore, extract content of your level 0 dumps
(and maybe higher levels - if you need) to newly created filesystems.
Such rescue system can be any kind of 4.x FreeBSD.
Then, move new disk to the target machine and boot it up.
If you haven't another system, try to use livefs CD-ROM (#2).
Some times ago I made replacement of hard drive in one of my systems.
But instead of dumps, I'v used real data from old drive.
Then I remove old disk and setup new disk as a primary boot disk.
All works fine. The only thing which can occurs - problems with
multiboot configs (i.e. FreeBSD and Windows 9x) due to LBA configuration
problems on some motherboards/BIOSes an HDDs. But it's not an issue in
you situation.
Hope this helps!
