CageOff: You will also need the kernel.
linux-msm-rhod-nand in ACL - Gitorious
You can clone it and begin you quest. Right off the top of my head id say you will need to fix USB code since i only enabled it for the Rhod. The board-file will need some attention as well to make sure a9 starts up before the rest of the system begins requesting information. You will need to port over some of the recent changes from the haret kernel I dont commit anything unless its rhod so other devices may be behind on our kernel.
best of luck, and let me know if you need anything else.
