Can you bisect the kernel or profile Xorg and see what's causing it? There haven't been any i2c changes in the radeon kernel driver in a while. I'm assuming it's only the kernel that you changed? E.g., just to be sure, does booting a different kernel with the same userspace components work correctly?
