There is a BIOS
update for your machine that deals with hybrid graphics. My initial search did not find many details though.

I wonder if the memory address conflict is due the Nvidia driver reserving that memory space? If the Nvidia driver could be disabled in the bios it is possible that that the memory could be freed up. It would be something to consider when purchasing a hybrid graphics laptop for OpenBSD use.
The last thought is if adjusting the usable memory for the intel driver affects anything?
