Devices below may experience a change in geometry. * Due to a bug, aic(4) never used extended geometry. Changes all drives >1G to now use extended translation. * sbp(4) drives exactly 1 GB in size now no longer use extended geometry. * umass(4) drives exactly 1 GB in size now no longer use extended geometry. For all other controllers in this commit, this should be a no-op. Looked over by: scottl
