  I think you mean't _X_HIDDEN. Using internal or private visibility is
most likely to cause obscure bugs. Talking about it, I have posted patches
and updated the related bugzilla entries several times, to allow compiling
everything with -fvisibility=hidden; this includes fixing several symbol
name clashes.

  But I don't think it would be the proper solution for this problem,
because the usage of hidden symbols should be an option, and if not
enabling it, it should just make all symbols visible.

  I think the proper solution should be to have a single AtomBios module
that would be shared by radeon and radeonhd. And probably compile it in
the server tree, somehow following the pattern of the different int10
