Well, this looks like you want to use the module system as a boot
loader. This is a nice use case :) It's like instead of loading and
booting a kernel image, you load and boot an ELF module. In this case,
if you are absolutely sure that no symbol is referenced from the root
COM32 module (you can see that by issuing a 'readelf -s' command on
your modules and inspecting the dynamic symbol table), and your module
also gains control of the system (including interrupts - COM32 also
registers an stub interrupt table that triggers the BIOS handlers),
you can discard SYSLINUX code without problems. In other words, if
your module is capable of implementing basic operating system work by
itself, SYSLINUX is not required.

Please let me know if there are any problems with that :)
