Hi Mattia, hi Dmitry,

Ok, I have now done the fllowing:
- recompiled a input-kbd binary with a relaxed version check
	-	if (EV_VERSION != version) {
	+	if (EV_VERSION > version) {
  in input.c, line 104 of input-utils.

- created a vaio-kbd from the output of input-kbd and changed the
  keys that hat keycode 470 and 471 (those shown in evtest 8)
  to key_brightness:

$ diff -u <(./input-kbd 8) vaio-kbd

remember:
evtest /dev/input/event8 reports code 470 and code 471 for the respective
Fn-F5 and Fn-F6 combinations.

Then I run
	$ ./input-kbd -f vaio-kbd 8
	/dev/input/event8
	map: 44 keys, size: 59/64
	parse error: /dev/input/event8
	$
with the effect that still brigthness is not working.

If someone can explain what is wrong here and how to get this fixed
that would be nice, because up to now on the sony-vaio mailing list
I heard many complains about disappearing brightness, I hope we can
fix that.

Best wishes

Norbert
