That limitation is true for the legacy power management implementation
(PowerOn/PowerOff calls in stream driver interface). However if the driver
supports the Power Manager interface it will be called synchronously before
any drivers are unloaded. At that point the driver still has full access to
the system and can do anything it wants (including communicating to an
application via a side channel).
