It is possible that the 180nm process happens to already have the thermal advantages of the 130nm process, and that new process merely improves on the speedpaths. You know, there's supposed to be two ends of the process, and sometimes the current process is tweaked with elements of next generation processes. For example, AMD's jump from cs44e7 to cs50 helped their thermals but did not seem to have a huge initial impact on actual operating frequencies.

It would suck, though, if Intel's jump from 180nm to 130nm did not help their power draw much. The Netburst family is somwhat heat limited in terms of frequency ramping, I have been told.
