Call i2c_init() before i2c_frequency() (since i2c_frequency() requires the object to be set up) and zero the I2C object before giving it to i2c_init() as i2_init() has to set up a default frequency for its timeouts to work and it will only do this if the hz field in the object was zero to begin with (otherwise you end up with a random but usually very large indeed timeout).
