I dont think your number for thermal limit for Thin and Lights is accurate. Samsung(?) has an Athlon-M-LV Thin and Lights with a thermal design point of 35 Watts.
Then, you named it, couple of other things like form factors come into play; heatpipes, optimized fans and airflow characteristics are in its juvenile stages presently. It ist just a matter of time when these things will be ready for the market. Some of them are already announced.

In essence, I would see the thermal limits of CPU in a Thin and Light design be closer to 50 than to 25 Watts. Should not be the bottleneck for A-64-LV.

Re: Dothan is currently speced at 21W TDP for 2Ghz

Do you have a link?

31 watts at 1.8ghz is what I've seen.

Perhaps your source is confusing amps (which are 21 for some of these cores) with watts?

By the way, a 2ghz Dothan is several quarters away, so even Intel many not know exactly how much power they will consume, at this point.

Opteron using ~20watts at 1ghz means it will likely be running around 1.3 to 1.4ghz at 31 watts when Dothan ships 1.8ghz at 31 watts.

That means thin&light 64-bit notebooks are going to easy, very easy, for AMD. OTOH, can you imagine a thin%light Itanium? Ouch! Quick! Hand me an ice cube....

Passing on SOI was one of the biggest mistakes Intel has made to date - it may end up dwarfing the whole RAMBUS screw-up.
