Beryl require significant amount of RAM access for the 3D chipset 
because each window is cached and updated as texture.

The regular 2D X only use one framebuffer in video memory, at a time. 
Only requiering like width x heigh x 4 bytes (32bit depth) of RAMDAC 
accessible video ram.

Beryl 3D X require width x heigh x 4 x num_of_windows_layers bytes of 3D 
chip accessible memory.
