I was talking this over with Kristian actually. Since we allocate the front buffer dynamically for KMS, we could probably let the maximum virtual size be 4k or so (which I think really is the 2d limit). In principle, well-behaved GL apps are supposed to check the GL_MAX_VIEWPORT_DIMS limit, since that's the maximum window size that's expected to work. So if compiz were well-behaved, it would refuse to run if the root window were larger than that. Whether compiz actually _does_ that is another question, of course. But I think changing the max virtual to 4k for intel 915 and 945 might be a less bad set of tradeoffs.
I remember when I used an ATI card (and binary fglrx driver) that had a 2kx2k OpenGL limit, compiz only drew a 2048 wide composited window on my 2560x1024 dual-monitor system. This was back in the X.org 7.0/7.1 days. I had a nice white gap on half of the right monitor where it didn't draw.
