  Log:
  Driver for the Apple System Management Console (SMC). This hardware is
  present on the MacBook, MacBook Pro, and Intel MacMini.
  
  This driver exports information via sysctl in its private sysctl tree
  dev.asmc.*. You can get information about temperatures, fan speeds, the
  keyboard light sensor and the Sudden Motion Sensor (SMS).
  The SMS is very useful to park the disk heads when the laptop is
  moved. Basically, the SMS is setup so that, under movement, we get an
  interrupt on irq 6 and a devd notification is sent.
