1.)
At this point the only quick solution is to move the old kernel and
System.map to "/" partition.  In case I need it I can always boot-strap
the system and copy the old file to "/boot"

2.) A permanent fix would be as you suggested, backup:
"world"
/etc (complete folder) to a another box, and re-install.

Since this is the same box, same processor.
Is it possible to "boot-strap" the current system, copy entire
"/"-partition to another box over ssh.

Fix the partition sizes and copy back the entire "/"- back to current box.
It would save me all the compiling time.
