If you'll try it in multiboot, be aware, that if cm9 is the second boot system, you won't be able to acces root.

There should have been a point in the settings, where you should have the possibility, but it wasnt there. Other user on xda, had the same problem.
This was the main reason for me to have cm9 as primary instead of White Rabbit.
I then saw how good it is and didnt install a second boot rom
