Is it the case that all compute capability 2.1 chips
have 48 cores per processor?
I can't get a clear answer from nvidia on this.

It will be 2 weeks until we know for sure; release date is 13th Sept for GF106 cards.
The GTS450 is expected to have 4 Streaming multiprocessors (each supporting 48shaders) for a total of 192 shaders. The core is expected to contain 32 texture-units. It supposedly has a 128 bit memory interface and 1GB RAM, but going by this page there might be 2 versions of the GTS450; so one might have more RAM, similar to the GTX460 cards.
As you can see it also suggests a GTS455, GTS440, GTS430 and GTS420, as well as 9 mobile cards.
Anticipate a GTX475 soon, probably just based on the GTX460, with a full shader complement (384).

In my eyes that's 14 new reasons to better seperate GPUs and CPUs on Boinc, starting with a Tab for each.

As SK said: so far the only CC 2.1 chip is the GF104. The other ones are not officially announced yet, which is probably why nVidia didn't give a clear answer.

However, I would expect the new smaller chips to adopt the same structure as GF104. But then nVidia didn't always listen to me in the past ;)

I'm not sure that's necessary. However, what I would like is the ability to assign projects to individual resources (CPUs, GPUs with different CC, ATI w/o dp etc.) first, including the definition of backup projects. Only after that should resource share determine the scheduling. IMO that would be enough of a separation.
