But.
What I'm trying to do is to have the EFI bootloader to chainload an
ext4 partition
where I have installed extlinux. The kernels and initrd lie alongside
the extlinux bootloader.

In a more schematic way:

1) the EFI BIOS loads the EFI syslinux
2) the EFI syslinux chainloads the extlinux that is on a separate partition
3) the extlinux loads the kernel & initrd that are colocated in the
same directory

point 2 is failing

I hope this is more clear than my previous, long, post :-)
