I've wrote about CONFIG_DRM_RADEON_KMS on my previous messages on devs
lists saying "As of Linux-libre 3.9, CONFIG_DRM_RADEON includes KMS
support by default, so i've removed CONFIG_DRM_RADEON_KMS from our
config files because it doesn't exists anymore.[0]"

Your problem is due to lack of firmware which newer kernel versions
made necessary for KMS. It is similar case than Jorginho.
