now i have a question:
  i know ppc is big_endian and pci bus is little_endian.i made a graphics pci card use big_endian.
  when i use graphics card to show QT 's picture through VGA ,the color is not what i wanted, it's inversed ,others are in right position.
  here below is what i want :
  #################################################
  0..................7  8............15 16..............24 25.................31 
           B                    G                   R                TRANS
  now it is this:
  #################################################
  0..................7  8............15 16..............24 25.................31 
        TRANS               R                   G                   B
  #################################################
   
  through mmap, the ppc display the screen color through direct pci bus control ,how can i change it?? 
  change kernel?? (i don't know where to change)
  or change others??
