Changed the way we're resetting the machine: we're now first trying the

keyboard controller method, and only if that fails we fall back to what
we have before.
At least my SiS laptop now properly reboots, and doesn't just halt
anymore - doesn't seem to have a negative impact on other machines, but
please report any regressions :-)
