devfs tried to fix this one by _getting rid_ of those numbers. Seriously - what are they needed for? (Yes, I know why they're needed with /dev on ext2) Opening a device in devfs went straight to the device from the inode - no extra lookup of "device numbers" Numbers were provided mostly for backward compatibility - they weren't used for the main task of accessing devices.
udev has many other advantages of course, too bad we still have to carry those numbers around.
