Maybe it is worth publishing a list of laptops OpenBSD works on? Or, maybe a list of ethernet cards. Is this purpose's project to maintain lists, or to try to make the code better as best as we can? I think it is better to just make things work as best we can, and let the market sort itself out. Managing the supply side is properly your burden.
