OpenVZ on Linode - Invalid kernel: elf_xen_note_check

I'm trying to install OpenVZ on my Linode. Here is what I did:

Step 1: Custom kernel

apt-get update
apt-get upgrade --show-upgraded

VERSION="2.6.32-28"

apt-get install linux-image-$VERSION-virtual

mkdir /boot/grub
(    echo -e "timeout 5\n" && \
    echo -e "title           Ubuntu 10.04 LTS, kernel $VERSION-server" && \
    echo -e "root            (hd0)" && \
    echo -e "kernel          /boot/vmlinuz-$VERSION-server root=/dev/xvda console=hvc0 ro quiet" && \
    echo -e "initrd          /boot/initrd.img-$VERSION-server" \
) > /boot/grub/menu.lst

# amend linode configuration

reboot

Step 2: Installation

function replace_in_file {

    TMP_FILE=/tmp/replace_in_file.$
    sed "s/$1/$2/g" $3 > $TMP_FILE && mv $TMP_FILE $3
}

apt-get update
apt-get upgrade

dpkg-reconfigure dash

apt-get install kernel-package libncurses5-dev fakeroot wget bzip2 module-assistant debhelper build-essential

VERSION="2.6.32.28"

apt-get build-dep --no-install-recommends linux-image-$VERSION-server
m-a prepare
kernel-packageconfig

Cores=$(Nr () { echo $#; }; Nr $(grep "processor" /proc/cpuinfo | cut -f2 -d":"))
echo "CONCURRENCY_LEVEL := $(($Cores + 1))" | tee -a /etc/kernel-pkg.conf

mkinitramfs -k 2.6.32.28-openvz -o /boot/initrd.img-2.6.32.28-openvz
apt-get install --reinstall grub-pc
update-grub

(    echo -e "timeout 5\n" && \
    echo -e "title           Ubuntu 10.04 LTS, kernel $VERSION-openvz" && \
    echo -e "root            (hd0)" && \
    echo -e "kernel          /boot/vmlinuz-$VERSION-openvz root=/dev/xvda console=hvc0 ro quiet" && \
    echo -e "initrd          /boot/initrd.img-$VERSION-openvz" \

sysctl -p

apt-get install --no-install-recommends vzctl vzquota vzdump

ln -s /var/lib/vz /vz

reboot

Finally, when I try to reboot my Linode I get this:

Any clue, what I could do wrong?
