I have the same problem. In fact, dri doesn't work (for me?) even if I drop X resolution to 1024x768 (glxinfo says direct rendering: No).
My workaround to this issue is to a) keep xlibmesa3-gl and xlibmesa3-glu (not to install xlibmesa-gl and xlibmesa-glu), hold their -dev counterparts in version 4.2.1-12.1 and b) divert thee tdfx_drv[1] away and take the tdfx_drv file from xserver-xfree86_4.2.1-12.1 package. Doing just a makes the dri work in 1024x768, doing a+b makes it work all the time. I haven't had problems with my Voodoo 3 earlier (espesially those mentioned in [2]). The problem is solved for me, but I do see this somewhat inconvenient ;).
