You'd still have to bypass the memory controller of the Intel chipset.
Anyhow, AMD and Intel cpus could run on the same chipsets....if they utilized the same memory bus, same cpu sockets, and same physical voltage. Back in the day they used to (though not perfectly, I think the AMD chips used to have a lot of compatibility problems with Intel chipsets, though I'm not sure about that, and VIA's chips still can use old Intel chipsets I believe).
As of right now, AMD and Intel use different sockets, different memory technologies, different cpu voltages, and AMD's memory controllers are integrated onto the cpu, while Intel's are on a seperate chip. One of the two would have to be bypassed...I know it's possible to bypass AMD's memory controller (but it's faster, so why would you?) but I'm not sure if you could bypass an external one. (it's also possible to bypass L1 and L2 cache, but that would hurt performance a lot as well)
Even Intel chips that use the same sockets, chipsets, and memory can often not work in the same motherboards due to voltage differences. For instance, the Pentium 4 and the Pentium M, or dual core Pentium 4s on older P4 motherboards. Or, coming soon, Conroe on P4/PM motherboards.
If Intel wanted to, they could make chipsets for AMD, which would basically consist of removing the memory controller and only utilizing the southbridge, but you still couldn't use AMD and Intel chips in the same motherboard. Nvidia, ATI, and VIA utilize the same chipsets across both platforms, though it's really only the feature set that's being duplicated. (though back in the day, VIA chipsets used to have very similar memory controller for their AMD and Intel platforms, but they still weren't the same and were pretty crappy chipsets)
