I think the current way of rebooting is rather ugly.  If i remember
well, cpu_reset() nukes the page table directory(s) or does some other
dirty trick causing the cpu to fall over.

We should instead use one of the documented methods to reset an AT,
e.g. via the keyboard controller.  I don't know if any of this will
also reset the ISA bus, at least it's much cleaner than only choking
the cpu.

Never trust an operating system you don't have sources for. ;-)
