Is this stuff normal?

Coolant temperature isn't the same as oil temperature. It can take much longer to get the oil up to temp, and until the oil is hot the condensation won't get burned off.
Post a photo of your engine, everyone loves engines. Plus we can see how your PCV/breather is setup. Getting ventilation through the engine is as important as getting it up to temperature.

Engine photos attached. Totally stock with fully functioning PCV system. Regarding the oil temp, I think I got it pretty hot last night on a five hour highway drive, but still had some white goo inside the oil cap after shutdown. No evidence of coolant contamination into the oil, as previously mentioned.
