This will only make more of the low 4GB space available for device
apertures, but doesn't solve the basic problem. Consider:
1. The NVIDIA driver supports up to eight devices per system.
2. NVIDIA has already announced a single card with 4GB of memory:
http://www.nvidia.com/object/tesla_c1060.html
Again, the driver can get at all the memory even when the aperture
is a fraction of the total size. None of the memory is wasted.
