FYI - time to mask ati-drivers above 12.4 if you're < Radeon 5400

12.4 is the last Catalyst to support Radeon HD 2000/3000/4000 series,
so if you're using them you probably want to;

# echo ">x11-drivers/ati-drivers-12.4" >> /etc/portage/package.mask

And if you're not concerned about 3D or power saving, maybe think
about using the "radeon" driver from xf86-video-ati.
