in photoshop preferences -> file handling you have option “maximize PSD and PSB compatibility” don’t know exactly what it does but maybe it will help
if you are making brush you will have to save it in lower version because brush files are compatible upwards (there are some free programs on net for that).

Also if you use some new abilities arrived just in CS4 or CS5, you cant expect you can open it in CS2. But if your file is rather simple or uses old effects kept sice CS2 it will give you some additional guarantees you can open it in previous versions. But you must know exactly which functions were in CS2 and keeped in CS6 etc.
To get 100% guarantee is the only way - open it in CS2. Ce est la vie.
