I could see issues with x86_64 dues to things like the pressure on the instruction cache and possibly the data cache if there are a lot of memory pointers. There are architectural advantages to x86_64 in higher-end Intel parts (think Sandy Bridge & Ivy Bridge) but in an Atom the simple in-order instructions and less sophisticated front-end may negate many of these advantages.
