Oh absolutely, this is not the reason I'm sure...just that I have seen this oddity at (rare) times with 1280x1024. I'm not aware of the disabling that you refer to.
When you set AA modes you are usually given some indication of the max resolution for that AA mode on a given card.. (does with the ATI control panel anyway).. If you go over that res AA is disabled because the card doesn't have sufficient vram to hold that many pixels. This can happen with any card and is ram size limitation. Unlike texture storage, the frame buffer can't be augmented by AGP accessible system ram, so go over the limit and the AA is turned off, rather than just getting slower, like with textures being accessed from the main system ram.
Sorry my quote usage doesn't meet your high standards for posting..
