201 Note copied from SX110 IS
202 GetBatteryTemperature usually will get back temperature of battery compartment/batteries. GetBatteryTemperature is implemented in Canon's firmware for SX120IS.
203 Firmware entry point is identified (0xFFC394D8) but function is not usable. Camera will crash if Canon's GetBatteryTemperature is called by CHDK.
204 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,
205 this function will be implemented as specific CHDK-code. It returns always with -99 (which means -99° Celsius or -146° Fahrenheit).
206 Original entry point in Canon's firmware is disabled (in stubs_entry.S).
