It is true that sam will validate changes to the kernel and reject illegal input. You don't need to use sam, but then the procedure varies from release to release and we do not know what release is involved here. With recent releases, the command kmtune would be used to adjust a value and kmtune also validates input.
I think malcqv is trying to understand how to recover is the new kernel does not work. That almost never happens anymore since kernel changes are vetted at input time. But you would interrupt the boot sequence and boot the previous kernel which is usually in /stand/vmunix.prev for recent releases.
