this works on our x86 laptops (via sysrq), so it's not broken by
design.
i think no one has looked into making it work on 1.75 yet, partially
because much of what one can do from olpc_ofw() (i.e., peek and poke
registers/memory/etc) is available from cforth, which runs permanently
on the service processor, the second core in the SoC. but it would be
nice to have it work.
