Running these experiments on any x86-lineage chip would obviously not work (except perhaps in a simulator) because of lacking the wider range of page sizes.

On a machine that has plenty of memory for what's running on it, a variation of the Navarro approach might still be useful even on an IA32/AMD64 machine. The OS would rarely feel enough memory pressure to consider splitting a large page.

Also, since Linux also supports architectures that have finer-grained page size steps, it should not look just at what IA32/AMD64 support. And once a popular OS like Linux supports it, the hardware designers at Intel and AMD can better justify adding additional page sizes to their hardware.
