  Hi Aaron,

  Can you test with a install of the current X Server git master, and
check what symbols are missing if any? Just use the script attached.

  I remember last year/start of this year, when I check, the nvidia
driver required miInitializeCompositeWrapper (don't remember if any
other symbols). Currently that function is not in the sdk, and the
apparently only user, libxaa has it as a hidden symbol, what probably
is wrong.
  libwfb may also need some update, wfbrename.h maybe should not be
installed, but I don't remember if the nvidia driver used it.

  xf86Rename.h probably should not be in the sdk, but bundled with
the drivers that provide fallbacks for older servers.

  I think all of these should always be available. And if one
compiles with --disable-xinerama, the xinerama function should
not be called.
