This is a clarification on my previous post. On a sony vaio vgn-fs790, whats strange is I cannot set the brightness using the settings on gnome-power-manager. However, I can explicitly set the brightness by running (as root):

echo "1" > /proc/acpi/sony/brightness
(for maximal dimming)

echo "8" > /proc/acpi/sony/brightness
(for maximum brightness)

Hopefully, that helps. I don't know if this is reproducible on other sony vaio laptops.
