I've done some digging and not found anythign Sabayon specific about this, but I have found this: https://bugs.launchpad.net/ubuntu/+sour ... bug/973297 which appears to be the identical problem... note that the "fault at address" changes from one boot to the next depending on if I plug in the USB dongle before or after boot.
This is the relevant output from the Xorg log file.
