What you can do is setup two X screens, and then tie them together with Xinerama.
Could we please have that limit extended? Although Xinerama does work, twinview was more stable. Just upgraded from 1920x1200 + 1600x1200 in tvinwiew to 2560x1600 + 1600x1200 in Xinerama. The previous setup had much fewer crashes.
