I tried using the RHEL6 kernel. Installed the vzctl, vzquota and vzdump packages from the normal Debian packages, then downloaded the vzkernel-2.6.32-042stab020.1.x86_64.rpm, used alien to convert it to a .deb, installed it, then built an initrd.img using update-initramfs.
I was able to boot a Xen domU VM using the new kernel, and again creating and starting OpenVZ virtual machines within it worked fine. However, checkpointing worked even less well than it did before; it caused a kernel panic which made the Xen VM reboot.
The domU's console showed this:
