If 32 bits is implemented, 24 bits is regarded obsolete. With most X11 
implementations, if there is a 24 bit and 32 bit option, 32 bit is used 
internally because it is faster, however it uses more memory. Think of 
it: there are 8, 16, 32 and 64 bit computers. For displays, 24 bit is 
there because it is 3 times 8 bit colors. The 4th byte in 32 bit is 
often used for additional information.

On 64 bits colordepth I think that's a case of not implemented jet. For 
speed and ease of implementation it might require 64 bit hardware...
