When running glxinfo with LIBGL_DEBUG on I get this
error message when it tries to load glide:
libGL error: dlopen failed: /usr/lib/libglide3.so.3:
undefined symbol: _trisetup_Default_win_nocull_valid

I had similar problem (but this was not the only one).
My patch mentioned in "Problems with AMD optimization"
solved it.
