Yes, I agree.
It appears that Juan Navarro, the primary author behind the Rice project, is working on breaking down the superpage benefits they observed. That would tell us how much benefit is due to page-coloring and how much is due to TLB effects. Here in our lab, we do have some (weak) empirical evidence that some of the SPECint benchmarks benefit primarily from page-coloring, but clearly there are others that are TLB limited.
