A short cut to this whole thing would be to work on getting a second head supported on a single X11 screen. Then 3D comes for free:

This solution provides Xinerama functionality without actually using the Xinerama wrapper.
Mmm, i am curious about this, how does it get handled in the XFree86 configuration file.
Possibly by adding a secondary monitor line to the "screens" section.
Also, i guess this would facilitate the memory management in dual head configurations.
Yes, the driver would need to handle how the memory is shared.
In general, dual head configuration is pretty poor in the current X
server, at least in the documented part. There is no way from specifying
mirrored or zoomed window output, or to be able to change the
configuration dynamically, but this would probably not be achievable
without an extension, or maybe incorporated with the RandR stuff.
If you want things to be dynamic, you will need to stay away from X's notion of a second X11 screen. That's is static and persistant by definition. However, a secondary "monitor" to the primary screen could be as dynamic as you want to make it.
I think that matrox did something such in their proprietary drivers.
There are other proprietary drivers that have also done similar functionality. However, I haven't seen anything in open source.
