i have indeed disabled quick/quiet boot options to no avail. i've also tried failsafe mode, ide vs ahci, acpi v1/2/3. the issue does not present with linux, which makes me wonder whether the openbsd kernel is somehow making some kind of hardware setting change that is not cleared on reboot. despite this only presenting in openbsd, i still blame hardware - but am hoping there might be some openbsd-related tweak. thanks for the idea.
