<I only read one or two articles on the subject, but I think Merced decodes and translates IA-32 instructions into IA-64 instructions. If this is incorrect, I hope someone can clarify.>

I don't know the details, but I'm pretty sure this is the case. Any IA-32 instruction gets fed into the little compatibility unit in the corner and gets translated into IA-64 instructions.

I don't think it's much of a big deal compatibility-wise. The good ole P6 core translates IA-32 instructions into internal RISC-like instructions. Same thing with the K6 and the K7. Almost no one implements IA-32 instructions directly anymore.
