What is the page size used by VirtualAlloc in 32-bit applications run on
64-bit Windows in WOW64? Is it the native page size as returned by
GetNativeSystemInfo or is it the "simulated page size" as returned by
GetSystemInfo?

If you don't mean dead architecture such as Itanium, x86 and x64 use the
same 4 KB pages. I would expect that under IA64, too, x86 apps get 4KB
pages.
