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.
