The official word from upstream is that the change to default AGPMode to "1" was a mistake, and it should be changed back to "4", since it seems to be more common. There is no reliable way to automatically get the right mode for those where it fails, so the only option for those is to either modify xorg.conf or play with BIOS settings.
