I have similar problem.
I find that after X server dlopen(3) the extension libdri.so with
option RTLD_GLOBAL, the symbols in libdrm.so which it depends on
cannot be accessed using dlsym(3), neither via the reference to
libdri.so, nor the reference to the global scope.

I have this little patch to make it work, but it seems not a best
way to do so.
