In my tests, I noticed that the output of `xrandr' moves the little star
when I switch from portrait to landscape and back:

   ~# xrandr
   Screen 0: minimum 240 x 240, current 640 x 480, maximum 640 x 640
   default connected 480x640+0+0 left (normal left inverted right x axis y axis) 0mm x 0mm
      480x640        50.0  
      640x480        25.0* 
      240x320        50.0  
      320x240        50.0  
   ~# xrandr
   Screen 0: minimum 240 x 240, current 480 x 640, maximum 640 x 640
   default connected 480x640+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
      480x640        50.0* 
      640x480        25.0  
      240x320        50.0  
      320x240        50.0  
   ~# 

This also seems to indicate that the refresh frequency is different
between the two, which may mean that the poweruse is different in
landscape and portrait mode.
