d thing about the 5200 is that it swaps bytes=0D=0Ato/from the PCI buss. =
 So if you write a 32 bit pixel, for=0D=0Ainstance 0x12345678, it will be=
 written to PCI as=0D=0A0x78563412.  Presumably this is based on an assum=
ption=0D=0Athat PCI targets will be little-endian.  So you might try=0D=0A=
reversing bytes and see if the palettes make sense.=0D=0A=0D=0AMark Chamb=
