This brings up an issue that I've been meaning to comment on. The use of phandle-valued properties in the aliases node causes real OFW implementations some amount of heartburn. The Open Firmware standard says that the properties in /aliases are string-valued. That's important, because aliases are shorthand for fragments of full device specifiers (pathnames that can include arguments to nodes). Phandles can point to nodes, but can't be relative, and can't encode per-node-component arguments. For binding a Linux unit number to a device node, I would prefer to decorate the node with a property like "linux,unit#", instead of breaking the standard semantics of /aliases.
