Wrong xserver is starting. The xorg fbdev doesn't support xv to my 
knowledge. You need to run the special VIA xserver to take advantage of
the via_chrome9 driver.

Normal :-(

I don't think the via_chrome9 driver will work so well with the openchrome 
xorg driver.

Ug. So the VIA X driver crushes with its own DRM driver. Nice :-(

Ug. So it only has HDMI/DisplayPort which is poorly supported at this 
time for the openchrome project. I'm nearlly done with the next xorg 
release so I will shifting my focus to supporting this in the KMS 
openchrome driver.
