Two things:
 1) There is too much data for a 4x4x8 image.  You should only have 16 bytes
    and you have 31.
 2) Although readhexstring should eat exactly as many bytes as you tell it
    thus leaving the showpage as the next thing in the input stream, I always
    worry when I see things like  ...hex data...ffe8showpage.  Use a newline!

This will display *something*... It should help you debug your mumble2ps
program.

%!

Good luck.
