Thank you both for your responses. The link to the kernel wiki was also worthwhile. In my all too quick research into writing a Linux Driver Model driver, somehow I missed the step of calling i2c_register_board_info() in the kernel startup code. I could register my driver with the i2c_core, but since there was not i2c_board_info entry nothing else happened in my driver. No that I have added the i2c_register_board_info call, my driver callbacks are called and I can get back to writing device driver code again. When my schedule frees up some, I hope I can write up description of the steps I took to get a new Linux Driver Model I2C device driver written.

Have you read Documentation/i2c/writing-clients already? That would be a very good start.
