It's hard to say without logs but I suspect you are missing the
contents of /etc/default/flash-kernel which according to your working
extlinux.conf in your case should should contain:
LINUX_KERNEL_CMDLINE="root=/dev/mmcblk0p1 ro rootwait"
This would normally be setup by d-i. You can either edit that file
directly or "dpkg-reconfigure -plow flash-kernel" in the chroot.
You might also be able to add console=tty there to override the default
serial console.
Ian.
