Well, that might not be the fastest way, but the following works just
fine to generate the initrd; all you need is debootstrap, binfmt-support
and qemu-user-static installed (I will assume you want and armel
kernel/initrd in this example, but the same should apply for other
architectures):

  debootstrap --arch=armel --foreign --variant=minbase sid rootfs-armel-sid
  cp /usr/bin/qemu-arm-static rootfs-armel-sid/usr/bin/
  chroot rootfs-armel-sid/
  debootstrap/debootstrap --second-stage
  echo "deb ftp://ftp.debian.org/debian/ sid main" >> etc/apt/sources.list
  apt-get update
  (You may want to mount /dev, /dev/pts /proc and /sys at this point.)
  apt-get install linux-image-versatile
  (And umount anything you mounted here.)
  exit

You should now have and initrd image in rootfs-armel-sid/boot/.

Yes, that's what I meant: have someone upload it for you, and then see
if anything fails. I don't think it's worth the trouble setting up qemu
images for every architecture supported by debian until you know there's
a problem, and have an idea of its nature. It might not even be able to
do anything about it if the problem is uninstallable dependencies.

For armel, <debian-arm@lists.debian.org>. I'm sure the other
architectures have similar mailing lists.
