The only thing that didn't work is the use of KDE4.1 applet to control

Hm, I have the same machine, and
xbacklight -set percent
works perfectly.
However Eva's suggestion worked:
sudo setpci -s 00:02.0 F4.B=00 ----> zero bright
sudo setpci -s 00:02.0 F4.B=FF ----> max bright
Yes, but in this case the X server won't notice the change. So when the
screen has been blanked due to timeout and then is shown again, the
brightness will always be set to 100%.
But in this way to use the applet and to automatically change
brightness in AC/battery modes. Why the backlight control via KDE applet
worked in 2.6.29 and not in 2.6.27 if sony-laptop module is the same?
Automatic brightness setting can easily be done via ACPI (ac_adapter event).
