I'm willing to work with Johannes and Niclas or whomever to get things working. Unfortunately, kernel hacking is a little beyond my skills. AFAICT, the drm-*-kmod ports all depend on the same gpu-firmware port, which as the name indicates holds all the firmware. It seems that drm-legacy-kmod needs to learn how to parse the new naming scheme (and may be a new scheme for packing the firmware into a *.ko file). -- Steve
