:)

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.

=46or those laptops, the patch forwards the ACPI event to the ACPI syst=
em
and can be later interpreted in userspace using
acpid's /etc/acpi/default.sh (example directly from Nilton):
