Well explosion may not be the right word........I am looking to post an ide-pre-patch test for reports. Once the reports come back with no errors related to the changes, that is when I would begin to press Linus to consider the additions of these chipsets for inclusion in 2.2.0. This would be done on a case by case basis with documentaion that each is stable. Should any or all fail this requirement.........they would appear in 2.3.X development to be resolved with the next 1xx revisions to get them right.........
