If something requires a library that is not present it simply will not work (as in, will not even start). There is no mystery or ambiguity to it. If the applications you mention run, then you are fine. You can check what libraries a binary needs to link with ldd. For example: > ldd /opt/VirtualBox/VirtualBox linux-vdso.so.1 => ...

To answer your last question first, x86-64 CPUs (a.k.a. Intel 64, AMD64, x64...; basically any laptop/desktop 64-bit CPU you can get these days) are fully backwards-compatible with 32-bit operating systems and applications. So a 32-bit OS will work on a modern desktop. As to why you should use 64-bit instead, the 64-bit instruction set adds various features ...

After a lot more searching I think I have convinced myself that there is no simple way to get what I want. So, what did I end up doing? I installed LiME from github (https://github.com/504ensicsLabs/LiME) git clone https://github.com/504ensicsLabs/LiMe cd /LiME/src make -C /lib/modules/`uname -r`/build M=$PWD modules The above commands create the lime.ko ...

I am assuming that your question is about x86 processor. Here is a compromise solution, that is used on Debian 32 bit. Produce the whole system for 32 bit, but also add some extra kernels: pea-kernel is 32 bit, but can address more than 4GB ( in theory up to 64 GB ) of physical memory, but only 3GB of logical (3GB per process, 1GB is used by kernel). ...

Can I be reasonably certain that a 32-bit OS will still work on a modern desktop? Yes. Almost all 64-bit capable processors support both 64 bit mode or 32 bit mode. (Exceptions might be early Itaniums, IBM power CPUs etc, but nothing mainstream.) Assuming that I will not be doing anything memory intensive, is there any other reason why I should use ...
