You can go back to the old kernel (/kernel.old). When you boot, you get the "twrily". Hit space. If you do the command 'lsmod' at the prompt you will see "kernel" with some info after it. There may be some other kernel modules loaded as well. Type the command 'unload' and do a 'lsmod' again. You should not get anything back. Type in 'load /kernel.old' to load the old kernel into memory. You can now do a 'boot' to boot into multi-user mode, or 'boot -s' to go into single-user mode. This procedure worked for me. YMMV. Further commands are available in the loader(8) man page. You can find the man page online [1].
