   After a bit more poking around, and some thoughts from Martin
Husemann, it seems I missed the point entirely. I thought X was
still running, but after starting it from a remote login I can see
that it is dying with:

/usr/X11R7/lib/modules/dri/r600_dri.so: Undefined PLT symbol "XML_ParserCreate" 
(symnum = 56)

   So now I'm guessing this has something to do with the expat move.
