As the in-kernel solution is undocumented it is not of much use to the
general user base, only to the guru who implemented it and his/her close
circle.
On the other hand, k-p comes with extensive documentation and there are
many howtos on the web.

Actually this turns out to be an issue with Debian kernels as well:
Setting up initramfs-tools (0.97.2) ...
update-initramfs: deferring update (trigger activated)
Setting up linux-image-2.6.32-5-686 (2.6.32-15) ...
Running depmod.
Running update-initramfs.
update-initramfs: Generating /boot/initrd.img-2.6.32-5-686
cryptsetup: WARNING: could not determine root device from /etc/fstab
sed: can't read /etc/mdadm/mdadm.conf: No such file or directory
E: /usr/share/initramfs-tools/hooks/mdadm failed with return 2.

run-parts: executing /etc/kernel/postinst.d/initramfs-tools 2.6.32-5-686
/boot/vmlinuz-2.6.32-5-686
For the kernel-package image nothing is logged:
Setting up linux-image-2.6.34-1-686 (2.6.34-1-686-10.00.Custom) ...
Hmm. There is a symbolic link /lib/modules/2.6.34-1-686/build
However, I can not read it: No such file or directory
Therefore, I am deleting /lib/modules/2.6.34-1-686/build
Hmm. The package shipped with a symbolic link
/lib/modules/2.6.34-1-686/source
However, I can not read the target: No such file or directory
Therefore, I am deleting /lib/modules/2.6.34-1-686/source
Running depmod.
Examining /etc/kernel/postinst.d.
Note that with k-p initramfs-tools are configured after the kernel while
with Dedian kernels they are configured before the kernel.
A postinst.d script is installed automatically:
initramfs-tools: /etc/kernel/postinst.d/initramfs-tools
--------------------------------------------------------------------------------
#!/bin/sh
version="$1"
bootopt=""
# passing the kernel version is required
[ -z "${version}" ] && exit 0
# kernel-package passes an extra arg
if [ -n "$2" ]; then
if [ -n "${KERNEL_PACKAGE_VERSION}" ]; then
bootdir=$(dirname "$2")
bootopt="-b ${bootdir}"
else
# official Debian linux-images take care themself
exit 0
fi
fi
# avoid running multiple times
if [ -n "$DEB_MAINT_PARAMS" ]; then
eval set -- "$DEB_MAINT_PARAMS"
if [ -z "$1" ] || [ "$1" != "configure" ]; then
exit 0
fi
fi
# we're good - create initramfs. update runs do_bootloader
update-initramfs -c -t -k "${version}" ${bootopt}
--------------------------------------------------------------------------------
The example script is different, though:
/usr/share/doc/kernel-package/examples/etc/kernel/postinst.d/initramfs
--------------------------------------------------------------------------------
#! /bin/sh
set -e
if [ -n "$INITRD" ] && [ "$INITRD" = 'No' ]; then
exit 0
fi
version="$1"
vmlinuz_location="$2"
if [ -n "$DEB_MAINT_PARAMS" ]; then
eval set -- "$DEB_MAINT_PARAMS"
if [ -z "$1" ] || [ "$1" != "configure" ]; then
exit 0;
fi
fi
# passing the kernel version is required
[ -z "$version" ] && exit 1
if [ -n "$vmlinuz_location" ]; then
# Where is the image located? We'll place the initrd there.
boot=$(dirname "$vmlinuz_location")
bootarg="-b $boot"
fi
#
if which update-initramfs >/dev/null ; then
update-initramfs -c -t -k "$version" $bootarg
fi

Indeed, it is well documented in current kernel-package.
Thanks
