Server aborting > My log has; # grep -i kms /var/log/Xorg.0.log [ 303.319] (II) [KMS] Kernel modesetting enabled.

Other than that, when you update xorg you also need to 'emerge @x11-module-rebuild' afterwards, but unless you've been emerging things out of order that's probably not this issue this time. If you're not sure, just do it anyway if its still broken after the kernel update. I have had a single instance where I needed to rebuild xorg due to suit a new kernel, but that was a long time ago.
