Are you sure of the chip type and the i2c address (especially the bus
number) ? The i2c busses are laid out differently on the new models.
Apple dropped their mecanism of adding 0x100 to the "reg" property for
devices on uni-n bus 1. Now, they have 2 sub-nodes "i2c-bus@0" and
"i2c-bus@1" (iirc) and devices laid out below that. Maybe you are
mis-parsing the i2c address ?
