@Graeme - that may not be the only thing going wrong for you, but this bug report is only about the xorg packages from a PPA. Please submit a new bug report using 'ubuntu-bug ubuntu-release-upgrader-core' after a failed upgrade attempt as that will contain the log files we need to analyze the problem.
