If I start my car when the air temp is 85^F, and let it idle on the driveway, it takes about seven minutes for the engine to reach the point where the thermostat opens -- in my case, a measured 185^F. This works out to a warmup rate of about 14^F per minute. It's my understanding that this is pretty typical of a 907 engine. So, if your car's temp gauge indicates overheating within a minute or two of starting from an overnight rest, I'd be very suspicious of the temp gauge.
Of course, you could have a bad gauge (or voltage stabilizer), and a bad thermostat....
