Fix a Debian packaging bug
Do not use mindi-boot.2880.img (which may not exist) anymore in mondorestore
Adds a debuging message for image_devs for mondo
Adds some useful log info for debugging at restore time in init
Debian stores its optimised libraries in /lib/i686/cmov now. (Andree Leidenfrost)
Fix a bug on lsmod | sed. (Andree Leidenfrost). As a consequence, lsmod is not used anymo

re in mindi (except for log). Replaced by /proc/modules. And the MODULES variable is now us
ed to avoid code duplication.
