There is nothing keeping the Core2Duo from having 32GB of Motherboard System RAM, it's just that Intel wants those folks to be targeting Xeon only systems and thus the more expensive ECC setups.
When Mac Pros move to 64 GB or 128GB you'll see 8GB or 16GB iMac/Macbook/Macbook Pro options. Hell, Apple has intentionally limited the Mac mini RAM options from 4GB -> 2 GB.
This is how they create hardware market segments.
It isn't that it's intentionally done for nefarious reasons. The memory designs are different, and the Xenon's use different memory as well. If Intel were to have all their chips of the present generation have the ability to use more RAM, they would all be using FB-DIMMS. Would you want that? I don't think so.
Cpu's and their chipsets that are designed for high end use in servers, and expensive workstations, have larger power supplies and cooling systems. Owners of such machines have a larger energy budget, and well as a higher budget in general.
Intel is doing what they have to. To keep costs down for mainstream machines, they have to cut somewhere. The same thing is true for power and heat.
The new Nehalem chips are the same there. The Xeon weight line will have three memory channels, while less expensive machines will have two.
If you want more, you will have to pay for it. Those are the design considerations that must be made.
It isn't that Intel is screwing the lower end user. Rather, it's that Intel is giving them lower cost systems from the cpu and through. That's what people want, and need.
