I think I have this problem too. The best I could get it was to have the right resolution. The refresh rate and all other options remain unavailable. In fact the refresh rate is reported as being 0 hz (Impossible). The graphics work alright and look good except for huge glitches (See attachment) every few minutes.
My hardware is <S3 Unichrome Pro VGA Adapter (rev 01) running fully updated Hardy 64.
