We had a very nice way of playing with the DT on OLPC laptops from OpenFirmware – https://wiki.laptop.org/go/Device_Tree_Hacking

And I am pretty sure we had something wired up in the initramfs so we could load a DT overlay from a file in Linux. You'd put in in your /boot partition. But can't find the docs right now.
