Thanks for answering.

Why is that "maximum size" setting needed at all? The real maximums are 
given by the hardware anyway (as you explained 2048 x 2048 or 8192 x 
8192, depending on whether you want to do 3D). You cannot budge those 
hardware constraints by changing a software setting.

I have a feeling that the "Virtual" keyword specifies a value that 
should be managed internal by the X server, not by the user. If the user 
wishes to span his desktop over two screens, resulting in a "Virtual" 
size of, say, 1920 x 1968, then why is the user needed to add up those 
values himself and put it in a configuration file?

If the "maximum size" setting is really needed, why not default to the 
largest size that has got all the features (in the i915 case: 2048 x 
2048)? If 3D is not enabled (e.g. because the server was compiled 
without), the default could even be 8192 x 8192. As I said, the user 
experience would benefit.
