So, it looks like DRI is not around, at least for OpenGL.

I don't think so (I assume that someone would have told you so already).
You could check if the Xserver tries to load the direct rendering:
% cat /etc/X11/XF86Config | grep -i dri
What does this return on your machine?
It is necessary that this file (XF86Config) contains something like:
Load "dri"
If it doesn't, then you ought to add it in /etc/X11/XF86Config
Section "Module" of this file will then look like this:
Section "Module"
# This loads the DBE extension module.
Load "dbe" # Double buffer extension
# This loads the miscellaneous extensions module, and disables
# initialisation of the XFree86-DGA extension within that module.
SubSection "extmod"
Option "omit xfree86-dga" # don't initialise the DGA extension
EndSubSection
# This loads the Type1 and FreeType font modules
Load "type1"
Load "freetype"
# This loads the GLX module
Load "glx"
Load "dri" <=============== somewhere in section "Module"
EndSection
If adding this line doesn't help or if it was present already in XF86Config,
then... you could have a look at the latest X log file - I assume it
is /var/log/XFree86.0.log - and check for error messages related to DRI.
What does your log file say?
Cheers,
Sylvain.
