You need to have an i2c_board_info struct to instanciate the driver from
your board support code. Pass in the driver's names and the addresses,
then call i2c_register_board_info(). You can also have a look at how
others do that in arch/arm/mach-pxa/*.
However, I'm not quite sure whether that mechanism is also valid for
kernel 2.6.20. If it isn't, you should consider updating to something
more recent.

Yes, that works for all devices connected to I2C.
