Just an update. I pulled out of my closet an old Pentium III and got it
to finally boot the new kernel. It reboots fine, but as I left the
printk patch in, it didn't get to the cf9 usage. I take it, it can
detect the level. And perhaps the issues is only with x86_64?

I have no problem with sticking in reboot=b in my development box. I
just wanted people to know that I had issues.

Maybe keep the current way and on reboot, have a pr_info() stating, if
your system doesn't reboot try "reboot=b" on the kernel command line?
