non-booting TEGRA on Jetson TK1 (-current)

I have a TK1 board running -current (successfully) as of November 1, and a second that I am trying to bring up to the bleeding edge. I copied the DTB file from the Linux4Tegra flash image onto the SD card image (armv7.img) for NetBSD and that gets me past U-Boot and into the kernel. Many of the devices are failing to attach, so am I supplying the wrong DTB info or did I just catch -current in a non-booting phase?
