Comment 81 for bug 314928

@bryce -- could you give us some insite into the x-servers interaction with the MTRRs here. It appears from the logs in the previous couple of comments that the x-server is also attempting to instigate and remove an MTRR for the AGP aperture. Yet it seems to be failing to create in in our case, but still managing to remove it on exit. There appear to be two errors in behaviour here from xorg:

1) it is removing the AGP mtrr regarless of whether it was it that installed it
2) when there is no mtrr at start it seems to fail to add one dispite trying

Perhaps you can point me to the right place in X or some docs as to the expected behaviour.
