Still one version short, but at it's kinda impressive that Debian's experimental branch contains current kernels:

  # grep experimental /etc/apt/sources.list
  deb http://ftp.debian.org/debian experimental main
  
  # cat /etc/apt/preferences.d/experimental
  Package: linux-base
  Pin: release a=experimental
  Pin-Priority: 800

  # apt-get update
  # apt-get install linux-image-2.6.36-rc6-amd64

Now, if it would only boot... :-)
