ChangeSet@1.743, 2002-10-11 12:02:20+02:00, Andries.Brouwer@cwi.nl
Since 2.5.32 the keyboard repeat code was broken.
The reason Vojtech broke it was the stupid name of a field
in struct kbd_repeat, namely "rate". Every sane person
expects that a rate has dimension [1/sec], but here the
"rate" is a time period measured in msec.
So, the patch below first of all fixes the code,
and secondly changes the name.
Since Vojtech used PERIOD as index, I also used period
as field name in the struct.
Half of the stuff below is actually from Alan Stern.
