[Bug 35319] Re: no Fn at all Vaio SZ1XP Dapper

[Marcin Debowski]

I've been trying to get it all to work on a Vaio VGN-SZ18GP machine. This model seems to be pretty close to SZ110 judging from the lspci listing I found on Ariel's page and thanks to Ariel and other contributors to this thread some of the functions (namely brightness) work already.
Here is a short summary what I have tried so far. I do not use Ubuntu but I guess at this level it does not matter that much. 

Kernel source 2.6.16 available for the updates with my distro (FC5)
already contains sonypi patched with ICH7 against type 3.  Loading this
module results in this:

sonypi: Sony Programmable I/O Controller Driver v1.26.
sonypi: detected type3 model, verbose = 0, fnkeyinit = off, camera = off, compat = off, mask = 0xffffffff, useinput = on, acpi = on
sonypi: enabled at irq=11, port1=0x1080, port2=0x1084
sonypi: device allocated minor is 63
input: Sony Vaio Jogdial as /class/input/input9
input: Sony Vaio Keys as /class/input/input10

The input Nos are not fixed ones. Any sequential loading and unloading
of the module makes the numbers increassed by 2 (so next time it would
be 11 and 12)

/dev/sonypi is present and Fn keys show response in log/acpi (just two examples to keep it shorter)
This is for Fn-F5 pressed once only:
[Sat May 20 14:05:29 2006] received event "sony/hotkey SPIC 00000001 00000010"
[Sat May 20 14:05:29 2006] notifying client 2163[68:68]
[Sat May 20 14:05:29 2006] completed event "sony/hotkey SPIC 00000001 00000010"
[Sat May 20 14:05:29 2006] received event "sony/hotkey SPIC 00000001 0000003b"
[Sat May 20 14:05:29 2006] notifying client 2163[68:68]
[Sat May 20 14:05:29 2006] completed event "sony/hotkey SPIC 00000001 0000003b"

and this one corresponds to S1
[Sat May 20 14:07:57 2006] received event "sony/hotkey SPIC 00000001 00000020"
[Sat May 20 14:07:57 2006] notifying client 2163[68:68]
[Sat May 20 14:07:57 2006] completed event "sony/hotkey SPIC 00000001 00000020"
[Sat May 20 14:07:58 2006] received event "sony/hotkey SPIC 00000001 00000020"
[Sat May 20 14:07:58 2006] notifying client 2163[68:68]
[Sat May 20 14:07:58 2006] completed event "sony/hotkey SPIC 00000001 00000020"

Unfortunately this is it. No functional response for any of the keys. 
Sonypid + spicctrl don't work neither but the first one gives this kind of messages:
./sonypid: Sony Vaio SPIC daemon version 1.9.1, Fev 20, 2004
Event: Fn-F2 Pressed
Event: Event unknown!
Event: Fn-F3 Pressed
Event: Event unknown!
Event: Fn-F4 Pressed
Event: Event unknown!
Event: P1 Pressed
Event: P1 Pressed
(the last one is after pressing once S1 or S2 – same message regardless which one)

The other driver, sony_acpi nicely works with writing 0..8 directly to /proc/../brightness.
Now, what am I still missing? Do I understand this right that Fn keys are correctly captured with sonypi but the follow-up action is not hitting the target?
