atkbd. Version 1.162 of GENERIC fixed this problem in April of 1999. Subsequent to that, the hints data was removed from GENERIC and move to hints files. All the hints file ever created have atkbd at the right location. This should have been removed just after RELENG_4 was branched (and likely around 4.5 in RELENG_4). MFC After: 3 days
