You need linux-kernel-firmware >= 20131106-0.2.git7d0c7a8
This need to be retested but here i can not reproduce with : linux-firmware-20140102-0.2.git52d77db.el7.noarch kernel-3.10.0-89 mesa-dri-drivers-9.2.5 xorg-x11-drv-ati-7.2.0-8.20140113git3213df1 xorg-x11-glamor-0.5.1-4.20140115gitfb4d046c
We believe this is already fixed but moving to 7.1
Retested on build : RHEL-7.1-20141006.1 linux-firmware-20140911-0.1.git365e80c.el7.noarch kernel-3.10.0-175.el7.x86_64 mesa-dri-drivers-10.2.7-3.20140910.el7.x86_64 xorg-x11-drv-ati-7.4.0-1.20140918git56c7fb8.el7.x86_64 xorg-x11-glamor-0.6.0-2.20140918git347ef4f.el7.x86_64 No longer affects: Radeon HD 8770 [1002:6650] All monitors attach with native resolution.
