But if the configs are the same, you need to do the same things, so
generate your ramdisk and see what happens. I do this all the time,
just use genkernel to generate the ramdisk and do all other things
manually. I just make oldconfig when I upgrade and do make Bzimage and
make modules and make modules_install and copy the kernel to the right
place and update my lilo.conf.
