I figured it out. The instructions at <http://www.mesa3d.org/
llvmpipe.html> seem to work. I had some difficulty getting 
LD_LIBRARY_PATH to stick, however... setting it from a script in /etc/X11/
Xsession.d doesn't work as it's reset by the time I log in. Eventually I 
logged in to a virtual console, set the variable, fired up X by hand and 
ran gnome-shell. The result is very buggy. I don't know if that's because 
mesa 8.0.4 (or one of its build dependencies) is too old, or whether 
something is being built wrong.
