  SVN rev 184842 on 2008-11-11 12:25:08Z by gallatin
  
  Avoid scheduling firmware taskqs when cold.
  
  This prevents a panic which occurs when a driver attempts to load
  firmware at boot via firmware_get() when the firmware module has not
  been preloaded.  firmware_get() will  enqueue a task using a struct
  taskqueue allocated on the stack, and the machine will crash much
  later in the firmware taskq thread when taskqs are started and the
  struct taskqueue is garbage.
  
  Not objected to by: sam
