That sounds fixable. Can you describe how you got to this point?

I would use http://wiki.laptop.org/go/Tiny_Core_Linux to boot from USB
and investigate the cause:
# cat /proc/mtd0
# mount -t jffs2 mtd0 /mnt
I would also make a backup using the xo-backup tool included on the Tiny
Core Linux build modified for XO-1. This is documented for XO-1.5 at
http://wiki.laptop.org/go/How_to_backup_your_XO#XO-1.5 but ought to work
in a similar fashion for XO-1 ... if you mount the jffs2 filesystem

Yes, except it isn't an .img.

Yes, the .tar.lzma does not have boot files in /boot, you need to create
the symlink to the versioned boot directory.
