(NB: originally rejected because Package: was not first, but I copied from your example in which Package: was also not first)
Performed a mostly default install of the current stable as of yesterday on a PIII with a single HD, which I specified should all be used and should be reformatted.
I selected only 1280x1024 for the screen resolution, that being the native resolution of my LCD monitor. When I logged in I was presented with only 640x480, 800x600, and 1024x768. And no means of expanding to my original 1280x1024.
