the linux reboot code is very strange and I determined a few years ago

triple fault scenario.

that's far and away the best way to reset a system.

The most acceptable way (nowadays) to integrate that into the kernel is as 
part of watchdog timer support. However it might be worth integrating into 
the power off/reset patches in freebios source tree.
