How do I bring up (embedded) Linux on a Tegra Ventana development board?

I have a Tegra Ventana development kit, on which I want to run Linux. (NVIDIA only makes Android 2.3 and 2.2 images available for the Ventana: see "Ventana Specific Downloads" at the bottom of http://developer.nvidia.com/tegra-ventana-development-kit.)

I found an announcement of the release of Linux For Tegra (L4T), which predates the release of the Ventana. I also found notice that L4T has been removed from NVIDIA's downloads page. So I guess if I want to run Linux on the Ventana (before NVIDIA eventually re-releases it) I'm going to have to build it myself. (Though that might be made easier if I can follow the breadcrumbs left by the "many of the community have already taken various linux distributions and got them up and going..." mentioned in the L4T announcement.)

How do I go about开发者_JAVA技巧 learning how to build Linux for this board?

I haven't been able to find any blog posts or mailing list entries from those people who have brought up various Linux distributions.

I did find http://tjworld.net/wiki/Android/Tegra/Linux/SourceCodeRepositoriesAndPatches#Linux, which gives me the Git URL to the Tegra tree (and the name of the maintainer). Lower down on that same page is a pointer to the linux-tegra mailing list. But I didn't find anything like a link to "getting started" instructions in the mailing list.

I'm reading Building Embedded Linux Systems, Second Edition (and have skimmed through Embedded Linux Primer, Second Edition), and perhaps I'll be able to figure it out for myself. (Though I suspect I'm going to get stuck because of the lack of technical documentation on the Ventana.) But I'd appreciate any advice to save me time.

Take a look at the people already running Ubuntu on Tegra 2 devices:
