Dear Mr. Preining,

If you are the wrong person to ask this, maybe you could refer me to 
somebody?

I am trying to understand sony-laptop and why (without 
CONFIG_ACPI_EVENT) Fn+F6 generates an acpi input event (button/fnf6) and 
Fn+F5 does not.

So far I traced both Fn+F5/F6 to this call. For Fn+F6:
	input_report_key(k.dev='Sony Vaio Keys', k.pey=471, 1)
And for Fn+F5:
	input_report_key(k.dev='Sony Vaio Keys', k.pey=470, 1)

"input_report_key" in include/linux/input.h seems to just call 
input_event(dev, EV_KEY, code, !!value);

Where value = 1, EV_KEY = 1, and dev = 'Sony Vaio Keys' and code = 470/471.

So why does the input_event call for FN+F6 (471) gets processes, but not 
for FN+F5 (470)?

If you can: Please just a little hint .... and Thanks!!

Knuth
