Yes, 130nm and 90nm desktop parts use a heat spreader, but not because it is all that efficient of a heatsink (In fact, many suspect that if you could remove it, you could cool the die better.) The reason for them is to protect the fragile cores from being cracked during installation. The are thin enough that they'll be far from uniform temperature: If you saw an IR picture of a 90nm and a 130nm A64, the 90nm would have a much smaller "square" of hotter temps in the middle than the 130nm part.
