Do you think a damn ethernet chip which >is near 1W "is not that small" ?

Olin stated that the package is not particularly small and should be capable of dissipating that power, he didn't say that the power dissipation was small! I think you are comparing apples and oranges anyway, devices that need to drive long cables at high speed do tend to have high power requirements.
