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

[Arnaud]

I.
As I was getting the same kind of trouble, I read sonypi.c and noticed that stelian was very accurate : type3 VAIO model is detected if an ICH6 chipset is found on the host. As my SZ1 has a ICH7, It falls back on a type2 behaviour.
I simply had this to drivers/char/sonypi.c: 

--- drivers/char/sonypi.c~      2006-04-18 19:58:19.878837000 +0200

                                          PCI_DEVICE_ID_INTEL_ICH6_1, NULL)))
                sonypi_device.model = SONYPI_DEVICE_MODEL_TYPE3;
+       else if ((pcidev = pci_get_device(PCI_VENDOR_ID_INTEL,

+               sonypi_device.model = SONYPI_DEVICE_MODEL_TYPE3;
        else
                sonypi_device.model = SONYPI_DEVICE_MODEL_TYPE2;

And now, I'm getting the following log at module insertion :

No more "command failed at drivers/char/sonypi.c" stuff

And events like :

Which is that I expected (am I wrong ?)

Please notice that I'm not a kernel guru at all so I don't know if it this the right way to do it...
Maybe stelian can validate/invalidate this can of patch (tested against 2.6.16.7 vanila).

However, I haven't tested yet if this still works after an hibernation. I'll let you know.
