Oh, I see. Search this list archive. Sometime last year someone posted how to do this. It's something along the lines of let yast2 do its thing, and then add another card to the graphics setup with basically all the same settings except for one or two small differences. I don't know the details though.

I tried that too, and SAX chews on it for a while and then eventually rejects the change... although it's possible that I didn't get the tweaking on the second "virtual" card quite right. C.
