Hi,

I've installed a new Debian wheezy on my sony fs315s. Previously, is was 
running an old gentoo on this one.

I'm trying to make fn keys working with acpi.

My kernel is the debian stock: 3.1.0-1-686-pae
My DSDT table is in attachment.
As for now, i've tried with things with sony-laptop module. I have the 
backlight support in /sys/devices/virtual/backlight/sony
I've tried the following module parameters: compat, no_spic
You can find below what syslog says with debug=1 compat=1 no_spic=0:

When i try to discover acpi stuff with acpi_listen; none of the fn keys 
are working (brightness, sound, switch to external screen, s1, s2).
The only thing i can found when i press such keys (and the logs below 
are the same whatever the fnkey is pressed) is in syslog;

Jan 21 11:43:38 vaio kernel: [76251.981919] atkbd serio0: Unknown key 
pressed (translated set 2, code 0xf5 on isa0060/serio0).

'setkeycodes e075 <keycode>' to make it known.
Jan 21 11:43:38 vaio kernel: [76252.085696] atkbd serio0: Unknown key 
released (translated set 2, code 0xf5 on isa0060/serio0).
Jan 21 11:43:38 vaio kernel: [76252.085701] atkbd serio0: Use 
'setkeycodes e075 <keycode>' to make it known.

When i execute acpi_fakekey 224 (KEY_BRIGHTNESSDOWN) or 225 
(KEY_BRIGHTNESSUP): it is working as expected.

Do you have some ideas to make these things working ?

Thanks and regards.

Waiting reading from you.
Cyrille
