You must have fixed it in CVS.  I just rebooted my machine and picked
up the latest versions I had compiled, and the brightness settings now
work correctly (and actually adjust the brightness).  I was a little
concerned at first, because all of a sudden my background image got
blindingly bright.  Turns out the old setting value of 100 was left
intact, but its meaning is now very different.  After adjusting that
to near zero on each screen, I am quite happy.

A nice little side benefit is that I can now adjust the images so that
they are very similar in brightness on my two monitors which I cannot
seem to adjust to match each other using the monitor controls.
