   i just happen to be in the lab since i wanted to test the earlier
suggestion, so i gave this a shot (with the original radeon driver).
this time, while /var/log/Xorg.0.log makes no mention whatsoever of
EDID (ostensibly a good thing),  the end result is the same --
my laptop is forced to 1152x864.

   the log file verifies that the laptop display is recognized as
1920x1200, the radeon driver adds that as a "native panel mode,"
outputs VGA-0 and LVDS are connected, followed by:

   ...
   (II) RADEON(0): Using fuzzy aspect match for initial modes
   (II) RADEON(0): Output VGA-0 using initial mode 1152x864
   (II) RADEON(0): Output LVDS using initial mode 1152x864
   ...

should i now try this with fglrx?
