You can, but you can't mix and match multi-sized clone modes with
multi-sized dualhead modes. I was thinking of doing something like:
option "metamodes" "1024x768-800x600-clone 1024x768-800x600-left"
adding the orientation to the metamode and then removing the
orientation option. they problem is you then need to add checks to
make sure you have enough framebuffer for all of the modes listed and
you might end up with some huge or weirdly sized virtual desktops.
PLus it just adds to the confusion. I also wanted to keep consistency
with other mergedfb drivers.

If you'd prefer it be on the left, you can always switch the
orientation of the crtcs. in my set up, crtc2 is left of crtc1. the
orientation of the crtcs doesn't really matter.

This isn't really feasible from the 2d drivers perspective. you could
move the start of the 3d viewport over so that its "0" would be on the
right half of the framebuffer.

If you are going to go through that effort, you might as well just
solve the problem for real and have the 3d driver just iterate over
each block of 2048x2048. see the dri-devel archives: "2048 limit code"
