Did you mean two monitors?

This works, but there are hw limits for the size of the area which can
be rendered too. This is 2048x2048 on chips up to rv280, but r300 and up
should support 2560x2560 at least IIRC, possibly more.
(It might be possible maybe for the driver on old chips to hack around
the 2048 limit, I think it would work if the driver would submit the
rendering commands multiple times, and hack up cliprects, color/depth
buffer offsets, and viewport matrix while doing so. However, I think
there would be problems with color tiling (needs to be switched off),
hyperz (the same), depth buffer reads / writes (probably does not work
with surface translation etc.))
