I think you are looking at the knoppix built-on-the fly
fstab.  Look at the etc/fstab under wherever it
mounted your fedora root partition.

It may be damaged beyond repair, but the only thing unique in
a boot partition is the initrd image and that only if you
need a scsi driver to boot.  If you have a similar box
you should be able reformat that partition while booted
from either knoppix or your fedora install cd in rescue
mode and copy the contents over from another machine.
If necessary you can rebuild the initrd image after
you get to the point where rescue mode sees the partition,
mounts the partitions, and lets you chroot to the old
system.

You might want to look at something like backuppc:
http://backuppc.sourceforge.net/ to keep regular backups
once you are running again...
