  21  * Note copied from SX110 IS
  22  * GetBatteryTemperature usually will get back temperature of battery compartment/batteries. GetBatteryTemperature is implemented in Canon's firmware for SX120IS.
  23  * Firmware entry point is identified (0xFFC394D8) but function is not usable. Camera will crash if Canon's GetBatteryTemperature is called by CHDK.
  24  * To avoid a crash Canon's GetBatteryTemperature must not called. As long CHDK general code do not distinguish between cameras that support or don't support GetBatteryTemperature,
  25  * this function will be implemented as specific CHDK-code. It returns always with -99 (which means -99° Celsius or -146° Fahrenheit).
  26  * Original entry point in Canon's firmware is disabled (in stubs_entry.S).
