Oh, and if I do try to switch the panel to 1024x768, it thinks it
already is there.  Switching to something smaller (800x600) and then
back to 1024x768 puts me back in 1280x768.

And then:
$ ./xrandr --output LVDS --mode 1280x768
./xrandr: cannot find mode 1280x768

Is this because we are "faking" out the driver for this mode?

thanks,
