What hardware are you on? The radeon driver had 64-bit issues on
amd64. Maybe Matrox has a similar problem?

The kernel side looks good.

Not only do you have to enable the "dri" option, you should also have a
DRI section, like:

Section "DRI"
        Mode    0666
EndSection

in your xorg.conf.

Do the /dev/dri/card* devices actually exist?

Have a look at  /var/log/Xorg.0.log, and see what it says about
dri/drm. Look for things like "drmOpenDevice", "[drm]" and "[dri]", and
for the string "direct rendering". If it says "direct rendering
enabled", then dri works.
