Control Buttons backlight disable?

[EvilXenu]

Anyone know how to disable the backlighting on the Control Buttons (ie. home/menu/back/search)? I've got Aldiko and when I read at night when it's dark, the backlighting turns on for these buttons which is very annoying. They are significantly brighter than the screen! Especially when I have Aldiko set for night mode.

I've disabled the Auto-backlight option but that appears to only affect the brightness of the screen.

Thanks!

I believe you have to root the phone to modify those settings.
