wallaby backlight - no control to raise display brightness?

[setter]

Hi I have updated my wallabyXDA 1 in ROM kitchen - works great but now have no control to adjust Brightness of LCD what am I doing wrong.

Used my Wallaby not for a long time, but as i remember right there wasn´t any possibility to adjust the brightness of the device with any ROM. Could be that it have done by any external program....
