  I had an older ThinkPad that used to do this, and I never solved it,
but I did find a work-around -- if I did "ctrl-alt-F1" to switch
to a text console, the keyboard brightness controls would work, and
then when I did "ctrl-alt-F7" to switch back to the X-window system,
the brightness would be preserved.
