Thank you, too, for flying xorriso. :)

So the size of the boot image alone cannot be the problem.

A high boot image address once was the reason for a boot
failure of Debian ia64. (Itanium, not x86_64. EFI, not BIOS.)
You may influence the address of the boot image by
--sort-weight 2 /isolinux/isolinux.bin
--sort-weight -1 /isolinux/isolinux.bin
The former pushes it to a low address, the latter to a high one.
For medium addresses you'd have to assign higher sort weights
to some data files or directory trees, and lower weights to some
others. So that the boot image sits in the middle.
Have a nice day :)
