Can you point out an example of how this is done for Open Firmware devices currently? In particular, how are the udev rules supposed to operate? They get a device path, use that to find additional information in /proc/device-tree (hope that's mounted), and then what? Do we hardcode the block addresses in the rules, for example @1400 and @2400?
