Shouldn't an ATI Rage Pro with 4 Megs on board be able to do 1280x768 resolution? The highest I can get the display setup GUI to offer is 1152x864 which seems like an odd setting?
Check the settings for monitor. You probably have your monitor set to "generic" or something incorect. You will be shown only resolutions that both your graphics card *and* monitor support. If you are using Gnome, try selecting "System Settings -> Display" from GNOME menues, than click on "Hardware" tab (I guess this is the same GUI you already used). If your monitor is not listed, just select one from the "Generic CRT" or "Generic LCD" lists (in your case 1280x1024 one, I guess).
