The magic modeline that got X working at 800x600 on my
Gateway Liberty:

ModeLine "800x600" 30 800 816 856 920 600 600 601 618


It could use some "tuning" but at least it is working at 800x600.

The Liberty uses the Chips and Technologies 65545.

Info from Gateway on the Liberty:

The system features a built-in, backlit, color screen which is a 10.4
inch, VGA DSTN display. This LCD screen provides sharp, clear color and
resolution. Tilt the unit's entire cover forward or backward to adjust
the viewing angle. There are sliding controls on the right of the screen
which control the contrast and brightness. 

For 640x480x16 (mode 12hex) the vertical frequency is 60Hz, the

On the Liberty screen only, it will support the following resolutions: 

* CHIPS 655DGX-VL/ISA 640x480x16
* CHIPS 655DGX-VL/ISA 640x480x256
* CHIPS 655DGX-VL/ISA 800x600x16
* CHIPS 655DGX-VL/ISA 800x600x256
* CHIPS 655DGX-VL/ISA 1024x768x16
* CHIPS 655DGX-VL/ISA 1024x768x256 

If you choose any higher resolution than 640x480 resolution and run on
the internal display, there will be a virtual desktop.
