This is the method that controls backlight on your vaio model. I can
attempt a patch over the weekend unless you want to give it a go first.
I don't see any obvious method to control timeouts compared to other
models and kbdbl_ctl->base needs to be 0 for your model.
What options to you have in windows to control backlight? Just always
on/auto/off?
