Careful with that. On Sun Openboot, the proper procedure is to delete the property and then create a new property. It seems that when you simply create a property on top of a previous property of the same name, it doesn't re-allocate the storage. So overwriting a string property with a longer string will trash either your heap or your device tree. I don't know if OpenFirmware/OpenBios fixed that tradition.
