Hi Bill.  I've just pushed out my tree with a bit of the device tree
probing working on the versatile platform.  It works with the QEMU
branch that Jeremy Kerr is maintaining.  Here are the git trees, and
the web page that describes how to build it:

git://git.secretlab.ca/git/linux-2.6 test-devicetree
git://git://kernel.ubuntu.com/jk/dt/qemu.git
https://wiki.ubuntu.com/KernelTeam/ARMDeviceTrees

I've got stuff working on real hardware too, but it's not fully baked
yet.  Right now qemu is the least trouble.
