+
+         The image can be extracted from the Fiasco firmware image.
+         Use the proprietary flasher to extract the image. The
+         opensource tool "0xFFFF" is not able to extract the zImage correctly.
+
+         The zImage defined here will be included in the OpenWrt rootfs
+         for kexec-ing of the Maemo operating system. The Maemo rootfs
+         has to be installed on the n810's "rootfs" MTD partition (MTD4).
