The poster explicitly asked about running a 64-bit apache and a 32-bit 
mod_frontpage.  That combination is pretty much not possible.  You could 
possibly try a hack by creating a 64-bit mod_frontpage_wrapper that used IPC 
to talk to another 32-bit process running mod_frontpage in some kind of 
32-bit apache env that you'd have to build, but that'd be a lot of work and a 
major PITA.
