Comment(by mikus):

 Yuan Chao asked me to add the following:

 I have a G1G1, and mainly run joyride builds.  Am *always* plugged in to
 AC.  Do not have wireless.  To keep my __wired__ connection (USB-ethernet
 adapter) alive, I disable "suspending" with 'touch /etc/ohm/inhibit-
 suspend'.

 Earlier than about a week ago (perhaps with 1611, definitely with builds
 previous to that) the screen on my XO did NOT exhibit "dim and brighten"
 cycling.

 Lately, though, I __am__ experiencing "dim and brighten" on my G1G1 --
 including today with build 1628 (which has some newer 'yum updates'
 applied).  My OFW is now at the Q2D12 level.

 [By the way, one night I erased /etc/ohm/inhibit-suspend, and left the XO
 just sitting there.  The XO soon suspended (power light started blinking)
 and the screen went to dim.  When I came back the next morning, the screen
 was STILL on dim.  I would have thought -- if the XO was going to save
 power by turning off the CPU, it ought to have *also* saved power by
 turning the backlight completely off.]
