IMO the i2c_register_board_info only works in quite static setups. Especially with I2C-Busses attached to hotplugable PCI devices this way doesn't work reliable any more.
The device come and go dynamically so you can't assume fixed mapping.

Can you specify the hotplugable?
1. A hotplugable i2c bus controller (say i2c_eg20t) with all fixed i2c
 devices connecting to it
2. i2c bus controller is fixed, while the i2c devices will be dynamically
 connected to it.
3. Both the bus controller and devices are dynamically hotplugged

I had scenario 1 in mind, but with more than 1 bus controller (say 2x i2c_eg20t). How can you set a fixed numbering if there are more controllers, each with maybe more than 1 bus?
Anyway, how can you provide a static bus numbering if there are more than one driver or more than one device per driver if the devices are hotplugable?
