But then you cannot declare devices on these segments and expect Linux
to instantiate them. You'll have to wait for the segments to be created
and only then you'll be able to create the devices on them (using
i2c_new_device()).

Also, what's the point of giving numbers to the segments in the first
place, if they don't correspond to anything?
