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.
