If you're booted into kernel.old you can just build a new kernel and run `make reinstallkernel` to replace the new (non-working) kernel without touching kernel.old. Same if you're booted into the new kernel with some sort of workaround and want to preserve the old kernel. It is 100% safe to replace or rename the kernel and modules, even the one you're currently running. Just be aware that you may have trouble loading modules afterward. If for instance you boot into kernel.old and then rename /boot/kernel.old to /boot/kernel.works as I suggested earlier, you won't be able to load kernel modules until you update `kern.bootfile` to point to the new location of the running kernel (`make installkernel` does this when it renames the running kernel to kernel.old).
