That nexus port is a different processor chip and chipset? Previous, when I did porting of ARM devices, I used to find devices with the same processor chip and similar device controller chips that and was using the kernel I wanted to use and port the those kernels. And if not the same devices, then port other modules that were for those controllers. For instance, your GPad used a Tele chip 8902 ARM11 processor. Something built for an ARM7 didn't work for an ARM11 (at least until the noted below).
But I think things are going to change for that with a recent linux kernel release. I think you may want to look up customizing LiveCD iso's... to build yourself an install with Linux kernel 3.8 and switch that kernel for one within the iso image... Then create an image to flash.
Today, Precise's linux-kernel is now at it's current version 3.5.0-25. But... Look at this linux kernel announcement:
http://arstechnica.com/gadgets/2012/...pport-with-it/
That is on Linux Kernel 3.7... and I'm using mainline Linux kernel 3.8 on 13.04 dev now. So if you wait for 13.04 to release... It may save you a whole lot of work.
Just a thought...
