This is due to the patch 035_tdfx_disable_dri_on_16mb_with_highres.diff,
which contains the comment:

   /* Disable DRI if using a 16Mb card with virtual resolution higher
than
    * 1024x768 because DRI does not have enough memory available for
textures
    * at higher resolutions, and will not operate correctly.
    */

See also http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=38717 .

Now, this is an odd explanation; 16 MB should be plenty enough for the
DRI at say 1280x1024x16. Mike, do you have a better explanation for this
limit?
