Note that due to things like cache line misses, looking at the code will
tell you almost nothing about which is *really* the "best" code...

Why do you need to cross-compile?  Just build the drivers as x86_64.  Pretty
much anybody who actually *cares* about performance has moved off 32-bit
kernels a while ago (unless you're stuck with an embedded 32-bit CPU).
