kexec is designed to boot arbitrary kernels. How well you can do that
depends on how close the system can be returned to a state similar to
reset, and how robust the kernel you are booting is.
If you can get /sbin/kexec to reproduce your normal boot protocol it
is likely you can get an newer kernel to boot an older one.
