(Get the code!)
This would be a kernel issue (not X.org/userspace). You would be much better off posting to something like dri-devel list or somewhere else that actually gets view from open-source radeon devs.
I have a system running Windows with a Radeon HD4550. I might try to tun a LiveUSB of 14.04 there to see if it boots correctly.
