Backlight control
Until support in is introduced vaio-fw21e-backlight2.sh script can be used.

One can set it as a backlight keys response defined in /etc/acpi/default.sh (  daemon is required) or just run it by hand.

There is also a legacy version which requires the rhd_dump tool which used to be present in the radeonhd driver (perhaps you could try building it?).
