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.
