 Testing joyride-2301.  With no options checked in Power screen of sugar
 control panel, the screen backlight switches off within a minute (less
 time than it takes for me to read a web page), and then I need to hit the
 "increase brightness" key several times to read for each extra minute.
 Irritating!!!  I prefer maximum brightness almost always. A touch of the
 glidepad should be sufficient to restore the backlight, but it doesn't.

 The backlight going dark seemed often to synchronize with me pressing an
 arrow key to scroll the page I was reading. Pressing a key should reset
 the timer, to keep the backlight on, not switch it off.

 With "Advanced Power Management" checkmarked (presumably ON then?), my
 battery lasted only 3.3 hours of steady usage activity until blackout (2.9
 hours to Red LED).  It originally lasted about 3.5 hours when I first
 received it late January 2008 (maybe build 650 or 656).

 The battery status icon in the frame is very coarse, changing only rarely,
 and possibly non-monotonic too.

 Don't make this build official.

 I have not tried "Extreme Power Management" because I usually need my WiFi
 connection alive to submit bug reports like this one.
