that did it thanks /etc/modprobe.d/radeon-kms.conf:options radeon modeset=1 I mind you I still get the initial: [drm:radeon_init] *ERROR* No UMS support in radeon module! And the plymouth splash screen goes from one mode to another and ain't what it used to be!) - but that doesn't matter. On loading, the kernel sorts things out. A assume if I now reboot into the previous kernel, that wont work - I'll just do it out of curiosity - but no probs - I'll now stick with 3.17.8-200.fc20.x86_64.
