www.guru3d.com had a pretty big archive of drivers...should be able to find something there.
uggh.. they've completely redone their downloads section now...used to be able to pick ATI or nVidia drivers and browse them all by release number by brand...now you have to pick a month/year for release and you get links to everything that came out that month. Not sure I like the new format....guess it will grow on me eventually. Here's a direct link to the archives page:
