Whew.. This also happened to me using the instructions here (using Ubuntu) and in using Linux Mint for wiki.nitdroid. I make it sure I was able to copy the rootfs to the 2nd partition, and copied exactly what was written bootmenu file. I reflashed the appropriate zImage-4 kernels for Froyo, and 3 for the previous rootfs. I did that in Ubuntu. None of them worked as I expected. Have used 3 microSD cards and repartitioned as said in this forum. Any help will do..
