I also let the car warm up until the water temp has got to near 90 and the oil temp has started to warm up, before I move off. I know this does take a bit of time, but I'm sure it is better for the engine. Most wear happens in the first 15 mins after starting the engine, especially if it hasn't been warmed up before any load is put on it.
The Gallardo has a dry sump, so I think it really does need a few minutes to properly start circulating the oil before stting off down the road. There is also no "accumulator" to give the engine instant oil pressure at the bearings etc, so warming up gives the oil get a chance to get to the bearings, valve guides and other important places.
I'm not sure about it being a "cold blooded" engine - yes it does run a bit cooler than some other engines I've had, but as it is a high revving, sophisticated multi-valve, variable inlet/exhaust engine, I like to let it really warm up gently before stressing it at all.
Previous (mainly Japanese turbos) cars I've had also had an air sensor which measured the air density as you turned on the ignition, and altered the fuel map and timing to optimise it for the conditions. I would guess that the Lambo engine must do something similar, so agin warm up time would let everything settle down.
