First of all people don't use NVIDIA crap for hosting platform (or any other use). Or at least they try to avoid it as much as possible. As you can see in your dmesg you have quite a lot of unsupported parts of HW (or badly working/set).
It's fault of other OSs' that NVIDIA plays game about "available open source drivers" and that they want to play it. Couple of NVIDIA developers said during interviews that they don't care about open source systems, they develop only for payed systems. And not only SW part is crap in their case ;-) Anyway bigger problem is on your side as you don't want to learn or see differences in OpenBSD design and why is that and more specifically why it's better. You're looking at it from the point of view of Linux and other systems because you think that there is everything fine in them and that it's secure.
