If anyone has any objections, please let me know. ------------------ From: Dave Airlie commit e9ced8e040ebe40e9953db90acbe7d0b58702ebb upstream. When UMS was deprecated it removed support for nomodeset commandline we really want this in distro land so we can debug stuff, everyone should fallback to vesa correctly. v2: oops -1 isn't used anymore, restore original behaviour -1 is default, so we can boot with nomodeset on the command line, then use radeon.modeset=1 to override it for debugging later.
