32bit-64bit

Which OS (or distributions) comes with 64-bit kernels (x86_64, SPARC64, PPC64, ..smth else?..) and 32-bit userland?

I want all small userspace programs (like ls, cat, etc) to be 32-bit, because they really no needs to be 64-bit. But OS kernel must be 64bit for using >=3 Gb of RAM. Also database programs (when using a lot of memory) can be 64bit.

64bit mode can hurt some programs, makes them bigger, eating (wasting) memory on pointers (especially in big abstract datatypes like list, tree, etc).

64 bit programss WASTES twice memory on EACH Pointer. I don't want it.

And the Question is not "Are the 32-bit programs needed when 64-bit porcessor is available". Question is "What OS comes with 32 bit userspace and kernels in 32/64 bit mode". Examples of such OS includes: Solaris/SPARC64, MACOSX/X86_64 (10.5)/....

I read on Wikipedia that Windows 7 on a 64-bit PC needs twice as much RAM as on a 32-bit PC. I understand why is that: every number stored in memory takes 8 bytes rather than just 4. That, in simple terms, means that your amount of RAM is reduced to half when you use Windows 7 on a 64-bit computer… >>> More
