[PATCH 5/8] Rely less on sanity of AT keyboards.

ChangeSet@xxxxxx, 2003-09-25 18:26:39+02:00, vojtech@xxxxxxx
input: Change AT keyboard to use hardware autorepeat and move
untranslating to the AT keyboard driver as well. Lower
PS/2 mouse default report rate. Fix repeat rate adjustment
ioctls accordingly, and update other files to reflect the
changes. This should fix most known keyboard problems in 2.6.
