I managed to complete the installation by continuing without a kernel and when the
'make the system bootable' step failed, go to a shell and exec
'apt-install linux-image-kirkwood', and then rerun the 'make the system bootable' step.
It seems to complete well the installation.
Although I changed in /etc/initramfs-tools/initramfs.conf: MODULES=most -> MODULES=dep,
because by default the installer chooses 'targeted' but when I installed the kernel
it seems it chosed 'generic' initramfs. (both options booted ok).
The relevant part of /var/log/installer/syslog seems to be this:
