Practically all desktop LCDs do have a single chip that eats VGA and
outputs LVDS. All you would need is a suitable ROM with modelines for it
to work with a laptop screen. But these parts run hot and come in
gigantic TQFP packages (when compared to the form factor of ICs in
laptops.)
Making a replacement card that fits in a laptop instead of the
motherboard is quite possible. Sadly, I have neither the time nor the
motivation since I already have a SpiderDuo :)
