Depends on how your firmware or OS sets up the memory protection hardware; see https://en.wikipedia.org/wiki/IOMMU

The same applies to the GPU. The rPi does not have an IOMMU, but most platforms OpenBSD supports do not have one either.

That said, based on other discussion here it seems this whole thread is a red-herring and there is no problem with the blobs, it's just that noone has written support for it.

If OpenBSD delivers the blob as part of their OS, they take moral responsibility for it (which, for good reasons, they don't want to take). On the other hand, you don't have to deliver a blob to support, say, a hard disk.
