I think that a lot of people are tryin to get the 800x480 resolution to work because at this resolution there is a one-to-one mapping between screen coordinates and LCD pixels. Therefore, no scaling or aliasing aritifacts will appear on your screen. A good way to check is to set your X-windows background to the default black and white checkerboard pattern. If there is not a one-to-one pixel mapping, you will see moire patterns (wavy looking lines) on the background. Of course, in linux, using X-windows, you can get any graphics card to display 800x480 by typing in the right modeline.
