ps(1) either elevates its priviledges during execution, or has some
other way of medling into the afairs of other processes that will
eventually need some higher priviledge status (either that, or I am
really out-dated on modern operational systems)

There lots of ways of finding information on other process, using
libkvm was the most recent option that I saw ;) might be worth taking
a look at it...
