No, this change is not correct. You *newly* point ARM drm2 users to use a port marked with "ONLY_FOR_ARCHS= amd64 i386 powerpc64" Do you think that this is correct behavior? So again. I have not a single problem with drm-legacy-kmod removal, I have not a problem with pointing users of supported architectures (by kmod-*) to right port. But I have problem with marking drm2 driver as obsolete for ARM architecture (without single rational reason) and/or by pointing ARM users of drm2 driver to not-existent port. Michal
