One unexpected thing about the 5200 is that it swaps bytes
to/from the PCI buss.  So if you write a 32 bit pixel, for
instance 0x12345678, it will be written to PCI as
0x78563412.  Presumably this is based on an assumption
that PCI targets will be little-endian.  So you might try
reversing bytes and see if the palettes make sense.
