After deprecation of graphics/drm-fbsd12.0-kmod I found that it is still supported fine on 12-STABLE with legacy /boot/kernel/radeonkms.ko from the base. While trying the driver from graphics/drm-fbsd12.0-kmod I was not able to use this card with gdm, only startx or x11/slim worked. On 13-ALPHA this card still works fine with deprecated graphics/drm-legacy-kmod. -- Marek Zarychta
