The only difference would be the transport for hotplug events, which is
infrastructure which needs to exist anyway to transport other
information between domains.

We'll see when the code's finished, but I see the code being:

	__init boot_devtree_setup()
	{
		devtree_add(boot_devtree_ptr);
	}

	hotplug_receive_event()
	{
		receive data
		if (op == ADD)
			devtree_add(data);
		else if (op == REMOVE)
			devtree_remove(data);
	}

ie. the mere difference in transport should be a few lines of code.
Rusty.
