Your problem is likely due to the fact that the Freescale part requires Repeated-Start I2C communication to do reads. The original Arduino two-wire library (TWI library used by Wire), did not support Repeated-Start.
I know this because I had to rewrite TWI for one of my projects to support Repeated-Start (interrupt driven, both Master and Slave). Unfortunately I've never gotten around to uploading my code, but someone else did essentially the same thing here (at least for Master which is what you need): http://dsscircuits.com/articles/arduino-i2c-master-library.html
Lose the Wire library and use their I2C library instead.
