Log:
Add the address of IDT in the configuration ROM. (i386/amd64 only)
A change to dconschat(8) will follow so that it can bomb
this address over FireWire to reset a wedged system.
Though this method is just a hack and far from perfection,
it should be useful if you don't want to go machine room
just to reset or to power-cycle a machine without
remote-managed power supply. And much better than doing:
# fwcontrol -m target-eui64
# dd if=/dev/zero of=/dev/fwmem0.2 bs=1m
