I could be wrong, but AFAIK, libXda.so is part of the proprietory /
commercial X server by Xi Graphics (www.xig.com), and is implementing
their "XiG-DirectAccess" X extension.  I have no idea, though, why your
glxgears is trying to load that lib...  Taking a quick glance at their
demo package (http://www.xig.com/Pages/Summit/Demos/DX-GoldLinux.html),
it seems that libXda.so is being pulled in by their implementation of
libGL.so.

Maybe you could check which libGL.so you have installed, and run "ldd"
on the .so file to verify whether it in fact depends on libXda.so (it
shouldn't, AFAICT).  Apparently, something went wrong during the Xorg
upgrade -- like some old libs not having been replaced properly...
(BTW, have you ever had "XiG Accelerated-X/Summit" installed, or have
you tried to install the demo version some time in the past?)

In case of doubt, I would reinstall the entire GL/Mesa stuff (i.e. the
specific implementations of the virtual packages libgl1, libglu1, etc.
that you were using while things still worked). 

Good luck,
Almut

P.S. Not exactly sure in what way the "radeon" X driver is involved
in the whole game: it claims to support 3D acceleration, but what
exactly does that mean with respect to OpenGL, GLX, DRI, etc.??
Dunno, sorry.  Wiser heads than mine will have to help you here... :)
