I do not see this option among your xorriso -as mkisofs arguments:

  -boot-info-table

It is necessary for the ISOLINUX boot image to work properly.
The file isolinux/isolinux.bin needs to learn its own block address
in the ISO image.

More problems which nevertheless should not have prevented bootability:

An argument "16" is missing here.
But xorriso is too old to even know the option:

The 6.0.2 images, which i have, were made with xorriso version 1.0.4.
  $ strings <debian-6.0.2.1-i386-businesscard.iso | grep XORRISO- | less

The package in Debian "testing" is supposed to be up-to-date.
Elsewise:
  wget http://ftpmirror.gnu.org/xorriso/xorriso-1.2.0.tar.gz
  tar xzf xorriso-1.2.0.tar.gz
  cd xorriso-1.2.0
  ./configure && make
  ./xorriso/xorriso -as mkisofs ...your.options...

These warnings are caused by option -J which produces a MS-Windows Joliet
directory tree. They are harmless, except if you want to extract all
files on MS-Windows and want to bring them onto a system that supports
symbolic links.

------------------------------------------------------------------------

Further questions in case the next try does not yet yield success:

What do you get from
  xorriso -indev /var/opt/newest.iso -toc
and
  /sbin/fdisk -lu /var/opt/newest.iso

Did you try to boot it as emulated CD-ROM or as hard disk?
Are there any complaints to see which give more details ?


Have a nice day :)
