  Modified files:
    sys/dev/dcons        dcons.h dcons_crom.c 
  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
