Is this issue still unresolved?

I'm running Fedora 18, with 3.8.11-200.fc18.x86_64 as the kernel, and:

xorg-x11-drivers-7.4-9.fc18.x86_64
xorg-x11-server-common-1.13.3-3.fc18.x86_64
xorg-x11-server-utils-7.5-16.fc18.x86_64
xorg-x11-server-Xephyr-1.13.3-3.fc18.x86_64
xorg-x11-server-Xorg-1.13.3-3.fc18.x86_64
xorg-x11-server-Xvfb-1.13.3-3.fc18.x86_64
xorg-x11-utils-7.5-7.fc18.x86_64
xorg-x11-drv-ati-7.0.0-0.9.20121015gitbd9e2c064.fc18.x86_64

I'm using an IOGear GCS1764 KVM. Don't know if that makes a difference.
