Die Erkennung ist gemeint, die Stabilität ist in Ordnung.
Irgendwie scheint es, man sollte sich gut überlegen, welche Variante man wählt, >4GB mit fragwürdiger IOMMU, oder <<4GB.

You have to edit a source file and recompile the kernel.
However, it won't work (to be precise, it will probably crash on boot, or
possibly afterwards) unless you have an IOMMU, and most Intel systems don't.
OpenBSD doesn't support the AGP/PCI-e GART as an IOMMU, and I'm not sure
if it supports VT-d platforms (which you probably aren't running anyway).
The only option here is AMD.
