Put the kernel and kernel-modules rpms in a directory, cd to that directory, then # yum install *rpm The post-install scripts will call grubby which will insert the proper GRUB menu entry. FWIW, there is no GRUB legacy equivalent for GRUB2's grub-mkconfig command so there isn't a way to generate a new one from scratch.
