There's quite a few reasons not to support 64K color modes, for one I 
would bet that some card manufacturers decided to do something stupid 
like put the 6 bit for red (6 bits for green being the supposed 
standard) and they can't do anything to mess up 15-bit modes except 
support the YUV color model maybe. And sometimes you could use that 
last bit on the 15-bit modes for some kind of internal game flag and 
personally i use 15-bit because i use some lookup tables for fiquring 
intensity of colors which would get really big in 64K modes.
