Is there any plan to make the radeonhd driver work on big-endian
machines?

I am particularly talking about the code that accesses the atombios
data structures, which are little-endian.  An example would be a
line like the following, from rhdAtomGetTables():

   unsigned int atom_romhdr_off =  *(unsigned short*)
       (base + OFFSET_TO_POINTER_TO_ATOM_ROM_HEADER);

This will retrieve the offset incorrectly byte-swapped on a
big-endian machine.

I think accesses like these need to be wrapped in a macro.
