You need a graphics card that is supported for DRI ("direct rendering
infrastructure").
Usually involves a small kernel module (DRM, direct rendering manager),
and a matching card driver for XFree86. NVidia and ATI both have these
as proprietary binary modules, you'll need a version that matches both
your kernel and your XFree86 version.

If you believe your card should be able to do 3d, and you have the
drivers installed, have a look at /var/log/XFree86.0.log, look for
messages like 
[drm] Initialized ...
[dri] Disabling DRI.
