Well, it's just a guess, but, given that the window managers (X-window, 
Windows, ...) work with at most 32 bit displays (8 bits red, 8 bits 
green, 8 bits blue, 8 bits alpha) and even if that wasn't the case, the 
gfx-cards ARE limited to 32 bits displays (read the specs...), 16 bits 
per component for display is useless! All displays are down sampled or 
dithered to 8 bits per component.

The only things I heard about with more than 8 bits are the hi ends DVD 
players with 10 bits per component, so I believe that MAYBE some hi end 
gfx-cards may have more than 32 bits display...
