:)

Well, it seems that on some Vaios (including Nilton's pcg-frv26 but not
only this one), the Fn key events aren't seen by sonypi or sony_acpi
GHKE method, but do generate an ACPI notify event.

For those laptops, the patch forwards the ACPI event to the ACPI system
and can be later interpreted in userspace using
acpid's /etc/acpi/default.sh (example directly from Nilton):
