I'm pretty sure I got a cl-gd7543 going once before by simply adding the
right chip magic number. It was on a Texas Instruments laptop of about
3-4 years ago vintage. The gl7543 is the Alpine I think. I had several of
the manuals somewhere, but threw them away just after selling the laptop.

If all you have to do is add a chip number then, I'm sorry, it might feel like
it, but you're not in VGA Hell! Just somewhere nearby, where the weather is
more pleasant.
