Base drm2 contained i915 and radeonkms. All of the drm-*-kmod ports contain both of these and do support in upstream AFAIK the subset of cards supported by the old base drm2. Please let me know if I am wrong! Now, for i915 I'd say the support for old GPUs in our port is pretty solid, radeonkms was somewhat shaky in the beginning but more recent ports DRMs have better support (i.e., drm-next-kmod and drm-devel-kmod). So one really wants as recent of a DRM as possible. We (as in: FreeBSDDesktop) have some older HW we test on but of course welcome contributions by others in terms of tests, bug reports, fixes, ... also in that area. We can and will refine recommendations based on user input. I believe we'd like to have as many people as possible on the LinuxKPI-based DRM as active work is going on there. Thanks, Johannes
