That -rc5+ is a custom-built kernel, not a Debian kernel. You should tune your kernel
a bit not to include everything in your initrd image and have some modules resides
under /lib/modules only.
If I remember correctly, you can configure below /etc/initramfs-tools which modules to
include in your initrd.
