My guess would be that this allows the processor to throttle down when
you are not actively using it. This technology is similar to what Intel
calls "Speed Step", and has been a part of the PPC family for a long
time. Usually this is defaulted to on when you are using a Powerbook.
This does cause a little bit of a slowdown when you suddenly start
doing something intense after a period of inactivity, but the ramp-up
is less than a second, so you probably won't notice it in most cases.
This could nicely explain the heat drop, especially if you have a DP
machine, as the second processor could almost shut down most of the
time, but be available for wake-up at a moment's notice.

Not sure if this is the appropriate forum but I thought I'd ask. I
noticed that (1) installing the CHUD tools, and (2) checking the "Nap"
box in the hardware preferences, causes my dual 1GHz MD to run at
about 34 C -- compared to around 57 C when the "Nap" box is unchecked.
Does anyone know what's going on? I was unable to find any
documentation regarding CHUD's hardware preferences on Apple's web
site.
