Actually, I'm not quite sure when the "DRI" option is taken into account and when it's not. On my computer (965GM) it is not ignored, Xorg.0.log says
(**) intel(0): Option "DRI" "off"
but glxinfo says
direct rendering: Yes
and yet my OpenGL screensaver (Busy Spheres) is down to about 1 fps as opposed to something reasonable without the option, so something must have been turned off. The comment # 6 I referred to in the previous comment was in bug 447892 and not this one. In that case the DRI option is clearly ignored. Maybe it depends on the chipset. It would therefore be nice to have your Xorg.0.log with KMS (i.e. no kernel option) and Option "DRI" "off" in xorg.conf in addition to the ones mentioned in the previous comment.
