Ok, finally have an update here.  With some guidance from AF we now know that:
1) The 64-bit ntdll is not working because wine64 overlaps with it in
memory (
2) Chrome/Steam only uses the 64-bit WoW64 "helper" for winver <= vista
3) The Win7 version of Chrome/Steam requires a feature we do not yet
provide (

It is now my belief that we can get this to work for WoW64, at least
for Win7 (and probably for newer winver).  However, we need to get
Chrome/Steam working in Win7 mode before we can proceed and properly
test WoW64 thunks.
