The result: success! The hacker has posted a detailed walkthrough explaining all of the challenges and how they were solved. "Using a Dremel, I cut out a most of the battery compartment as well as some posts that on the case for the LCD that would no longer be needed. Doing so, the Pi sits flush with the back of the DMG case. ... The screen was the first challenge. The screen runs off 12V out of the box which wouldn't work with the USB battery pack. The USB battery pack is rated at 5V, 1000mAH so the goal was go modify the screen to allow it to run at 5V. ... I finally got it to work by removing the power converter chip as well as soldering a jumper between the + power in and the resister on the top right."
