I had assumed that because 64-bit wine did the “Program Files (x86)” thing, it ran 32-bit Windows apps in a 64-bit process. But now that I think about it, that doesn't make sense. WINE needs kernel and userland support for running 32-bit x86 code unless it adds an emulator, because WINE actually loads the Windows executable's binary code into the current process (I assume exec() is a good comparison?) together with OS shared libraries.
