      Oups, the array has been wrapped in my previous post
      and is not readable. Here they are again :


  Hexadecimal values

 Colours   640x400 640x480 800x600 1024x768
 --------+---------------------------------
  4 bits |    ?       ?     0x302      ?   
  8 bits |  0x300   0x301   0x303    0x305 
 15 bits |    ?     0x310   0x313    0x316 
 16 bits |    ?     0x311   0x314    0x317 
 24 bits |    ?     0x312   0x315    0x318 
 32 bits |    ?       ?       ?        ?   


 Colours    1152x864 1280x1024 1600x1200   1400x1050
 --------+------------------------------
  4 bits |      ?        ?         ?           ?
  8 bits |    0x161    0x307     0x31C         ?
 15 bits |    0x162    0x319     0x31D         ?
 16 bits |    0x163    0x31A     0x31E       0x314
 24 bits |      ?      0x31B     0x31F         ?
 32 bits |    0x164      ?



  Decimal values

 Colours   640x400 640x480 800x600 1024x768
 --------+---------------------------------
  4 bits |    ?       ?      770       ?   
  8 bits |   768     769     771      773  
 15 bits |    ?      784     787      790  
 16 bits |    ?      785     788      791  
 24 bits |    ?      786     789      792  
 32 bits |    ?       ?       ?        ?   

 Colours    1152x864 1280x1024 1600x1200   1400x1050
 --------+------------------------------
  4 bits |      ?        ?         ?           ?
  8 bits |     353      775       796          ?
 15 bits |     354      793       797          ?
 16 bits |     355      794       798         788
 24 bits |      ?       795       799          ?
 32 bits |     356       ?




 Key: 8 bits = 256 colours, 15 bits = 32,768 colours, 16 bits = 65,536
 colours, 24 bits = 16.8 million colours, 32 bits - same as 24 bits,
 but the extra 8 bits can be used for other things, and fits perfectly
 with a 32 bit PCI/VLB/EISA bus.
