I have one of these cuties.

However, I've used it mostly with Linux on a PC.

Yes, I know it sounds backwards, but that's what I did.

I seem to remember that I had to make an adapter cable

using resistors for the Hsync and Vsync.

I also used a custom modline to achieve higher resolution,

something like 700x400. If someon's interested I can try

and find the exact modline for you.
