Hope this helps!
Your other mail mentions switchable graphics. And I assume that the dedicated GPU is an nvidia by your dmesg. Does your comment in the previous mail about disabling switchable graphics still let you boot successfully? I'm not shocked this doesn't work. nvidia support is quite limited. I've tried OpenBSD on some machines with nvidia, and it's worked "ok". I've had other instances where it just hasn't worked at all (in similar ways to what you describe). The bottom line is that when I'm considering hardware for running OpenBSD, I pretend nvidia doesn't exist.
