That need has been met by the x32 ABI for some time now, it combines some of the best parts of the x86_64 arch with the lower memory consumption of 32bit (still limited to 4gb max memory though)

Does anyone use x32 ABI though? I once asked and only crickets answered. I'm experimenting with my own Linux distribution and was wondering if it is worth the time investment.

4GB max address space per process. It should support much more memory through PAE [1], which makes things more reasonable.
