MPU-9150 and 9-DOF with UMPL library

For what I'have seen using Motion Fit SDK, new MPU-9150 is able to provide 9-DOF data fusion. This is great, but there is no public available library to port the device on platform different from TI MPU 430 (currently used in Motion Fit Demo Board).

I'm currently testing MPU-9150 with UMPL library released for MPU-6050 on a PIC32 micro; I can confirm the library works with 9150 as much as with 6050.
The only problem I still have is that I'm not able to read compass data and not able to have 9-DOF data-fusion; which is the same problem I had with 6050.

How is it possible to use UMPL library for MPU-6050 with MPU-9150 having 9-DOF data-fusion working?
How can I access internal compass data for MPU-9150?
Which is the I2C address for internal AKM compass device?

Thanks for any support.
Paolo.
