sony-laptop: ACPI Exception when a Fn-Key is pressed

[Rodrigo Luiz <rodrigo@xxxxxxxxxx>]

Hi.

I have a Vaio VGN-FW235J and I tried today the latest kernel version
in git to test the latest changes in sony-laptop.

When I press any Fn-keys, i.e. brightness control, I received these
messages in syslog:

ACPI Error (hwvalid-0186): Denied AML access to port 0x00000080/4
(DMA1 0x0081-0x0083) [20090320]

Some information from dmidecode:

My dsdt is attached too.


I tried the kernel 2.6.29.1 and no errors occurs in syslog. But I need
to apply this patch to get the Fn-Keys events:
