VIA CLE266 DRI support ?

[Joel Carnat <joel@xxxxxxxxxx>]

Hello,

I've just installed DFBSD 2.4.1-RELEASE and Xorg via binary packages (as described in the HandBook).
So far X starts but DRI doesn't seem to be available:
(EE) [drm] drmOpen failed.
(EE) CHROME(0): [dri] DRIScreenInit failed.  Disabling DRI.
(EE) AIGLX error: dlopen of /usr/pkg/lib/dri/swrast_dri.so failed (Cannot open "/usr/pkg/lib/dri/swrast_dri.so")
(EE) GLX: could not load software renderer


The kernel says "agp0: <VIA 862x (CLE266) host to PCI bridge> mem 0xe4000000-0xe7ffffff at device
 0.0 on pci0" but there's no dri/drm related information. None in sysctl either.

Does Dragonfly support DRI/DRM for VIA Graphical Chipset ?
If so, how am I supposed to enable it ?

TIA,
  Jo
