For those that might be interested, I went out and bought an AMD Athlon II X3 435 CPU today. I can confirm by the batch code that it's infact a crippled Deneb core, though I'm sure that there are just as many crippled Propus (no L3 cache on the chip) cores too. My particular sample does not unlock but the price however is very good at just £42 from Yoyotech.
