$ xrandr
Screen 0: minimum 320 x 200, current 1920 x 1200, maximum 4096 x 1440
...

This is on a i965 chip. But I'm sure the vertical resolution could go 
much above the 1440. In any way, 2048x2048 is only the limitation of the 
3D engine, if you don't need OpenGL (compiz, games etc), the limit is 
much higher. And i965 has the 3D limit at 8192x8192, only older chips 
have the above mentioned 2048x2048.
