You need to use xorriso to do the isohybrid trick. If you look in the
file ".disk/mkisofs" on any official Debian CD, you'll find the exact
command line that was used to master the CD, to help in exactly this
kind of situation. You can safely ignore the jigdo pieces; the bits
you need for the isohybrid stuff are:
-isohybrid-mbr syslinux/usr/lib/syslinux/isohdpfx.bin -partition_offset 16
