Elmer, looks like Hammer will have a power dissipation of 70W. That's more than I thought.

In the case of AMD's development of the Hammer technology -- the upcoming x86-based 64-bit processor -- SOI enables significant improvements in the number of transistors on a processor. For example, a hypothetical desktop processor using 70 watts will run an AMD bulk silicon processor with about 40 million transistors. Our 64-bit desktop processor, the AMD Athlon based on Hammer technology, will operate approximately 100 million transistors at the same 70 watts.

It doesn't say at which frequency these "hypothetical" parts will run. If 70W is at the starting frequency (2GHz), that won't exactly bode well as Hammer ramps. Though it is worth mentioning that the 100M transistor variant of Hammer is likely to have 1MB of cache on it. While the cache isn't the largest consumer of power on the chip, the 256KB desktop chips are likely to have lower power levels.
