It sounds like the system is now partially 32 and 64 bit without much 
hope of stability. You might be able to backup your home directories to 
DVD or tar the content to an external drive.

For the rpms installed, /var/log/rpmpkgs might be useful for what is 
installed for a clean install reference.

I would be interested in what is in anacdump.txt.
