This is very weird, the keypress event (as opposed to the repeat or
release event) should be instant. Could you try running the module with
ir_debug=1 and send me the output of dmesg after such a run. It would be
good if you could combine it with evtest so that there are timestamps to
correlate the different key events.

This looks like it should as far as I can tell...400 ms from first
keypress until the first repeat, and then a key release event about 75 ms
later. The delay until the first repeat event can be changed using kbdrate
with the "-d" parameter.
