Yes, something like that.

Real hardware usually isn't really random either, it's just
unpredictable.  In most cases, accessing unimplemented IO registers
will read as 0, and writes are ignored, but there could as well be
hidden IO registers that are used during manufacturing tests, or for
hardware debugging.

Never trust an operating system you don't have sources for. ;-)
