The package linux-tegra is now in the repository, which is the first break away from something 2.6. It won't be replacing kernel26-trimslice until 3.1 is finalized and we have the bugs worked out. At which time there will also be an official tegra rootfs tarball, so no more piggybacking on OMAP. This first version is based on 3.1-rc3.
Install it, use it, love it, break it, let me know what doesn't work so we can get this the best it can be.
