--- Comment #11 from Mike Cloaked mike.cloaked@gmail.com --- For completeness I removed the radeon module from the initial ramdisk, and added:
install radeon /bin/false
to the file /etc/modprobe.d/blacklist.conf
Now the system boots to a working graphical screen for kernel 3.13.7 with only the Intel i915 running.
