initramfs-tools >= 0.94 installs a postinst hook, however it 
unfortunately appears to bail out early, if called from an official
Debian kernel image (/etc/kernel/postinst.d/initramfs-tools):

# kernel-package passes an extra arg
if [ -n "$2" ]; then
	if [ -n "${KERNEL_PACKAGE_VERSION}" ]; then
		# exit if custom kernel does not need an initramfs
		[ "$INITRD" = 'No' ] && exit 0
		bootdir=$(dirname "$2")
		bootopt="-b ${bootdir}"
	else
		# official Debian linux-images take care themself
		exit 0
	fi
fi

and therefore doesn't actually create an initramfs image anymore, after
the corresponding code ($ramdisk_cmd et al.) has been pulled from 
debian/templates/temp.image.plain/postinst.

I think this needs to be prepended by the full install path, like:
   if ($initrd && ! -e "${realimageloc}initrd.img-$version") {
