Yes, thank you for the hint! Replaced i2c_read16() with
i2c_smbus_read_word_data() calls.

Interestingly now, replacing i2c_write() calls with
i2c_smbus_write_byte_data() did _not_ work (hardware initialization
failure). I guess this is due to the differences between i2c and
smbus, and the hardware only handles the former correctly?
