Fab thanks. If I had a more formal testing session I would have  
reported it to you directly, but I've only recently got this XO  
running with that build to a state that I was able to use more  
regularly.

Incase it rings any bells, thought I'd just mention that screen  
dimming has now stopped altogether for me. I've reset powerd pref  
changes back to the default but no luck. It still powers off the  
screen, but no back-light auto-dimming. The closest I have to narrow  
things is that I noticed the dimming seemed to stop after I manually  
adjusted the screen brightness with the keyboard (maybe I tried to  
adjust it when it was already auto-dimmed, or some such permutation).
