Debian doesn't support them with a big binary blob; by default, it supports nvidia chips with an open-source driver (nouveau), which works fine for most things other than 3d gaming. It just hasn't been ported to OpenBSD yet, though there is interest in doing so [1]. [1] http://www.openbsdfoundation.org/gsoc2014.html#nouveau http://www.openbsdfoundation.org/gsoc2014.html#nouveau
