--- Comment #39 from jimis hol <hol.jimis at gmail.com> ---
As noted in https://bugs.gentoo.org/show_bug.cgi?id=458746 and Tom wrote
removing intel_modeset_disable(dev); from sys-kernel/gentoo-sources-3.9.6 made
radeon visible again. Going to 3.10.0, however, even if
intel_modeset_disable(dev); line isn't present in 
drivers/gpu/drm/i915/i915_drv.c disappears radeon screen again.
