One thing Achim: for 9100E 1.8GHz, voltage/vid and so amperage won't be the same as 9500 so power consumption can't be simulated unless you have the unlocked 9600. In that case you can throw voltage to sub-1.1V (my 95W 9600 BE is 1.192V at 1.2VID stock).

So your volts/amps at 1.8GHz would have to be maximum 1.085V at 15A per core to simulate those 65W models and NB speed slower than CPU speed by at least 200MHz and thus low IMC voltage and VID. I should be able to test something similar soon but still not as low.
