I finally tried building syslinux with the patches I got from Debian and it worked.

--> and chose those against 6.03 so I don't need to play with GIT tags.

For the record

- 6.03 build --> coulnt build on slackware-current
- 6.03 binaries --> Failed to load ldlinux.c32
- 6.03 debian patched build --> works!
- 6.04-pre1 binaries --> Failed to load ldlinux.c32
- 6.04 git build --> Failed to load ldlinux.c32

Didier, when it works, SYSLINUX is in fact easier than GRUB.  What a nice syntax we have there!  And the bootcode install process is not particularly hard either.

Oh and for my originating question on `/` vs `/boot/booting` on a single root partition, it's also solved.  I now host the second stage bootcode in `/boot/syslinux` without an issue.

        dd if=./bios/mbr/mbr.bin of=/dev/sda
        ./bios/extlinux/extlinux --install /boot/syslinux/
        cp -f ./bios/com32/lib/libcom32.c32 /boot/sysliunx/
        cp -f ./bios/com32/mboot/mboot.c32 /boot/syslinux/

and if one also wants the menu to show up, `libutil.c32` and `menu.c32`.

	vi /boot/syslinux/syslinux.cfg

	default XEN
	prompt 1
	timeout 50

	label Linux
        	linux /boot/vmlinuz
       		append root=/dev/sda1 ro vt.default_utf8=0 mitigations=off vga=791

	label XEN
        	kernel mboot.c32
        	append /boot/xen.gz dom0=pvh dom0_mem=1024M,max:8192M loglvl=info noreboot=true --- /boot/vmlinuz console=tty0 root=/dev/sda1 ro vt.default_utf8=0 mitigations=off vga=791
        	#--- /boot/initrd.img

Thank you both for your support
