I think what Sander is saying is that yes X may be trying to use the on-board video card because that it what it finds first that supports acceleration. It's plausible. I'd wonder how to coax X into logging more information about what it's doing. IIRC the dump in your original e-mail showed some sort of stall in the via driver's routine to wait for a vertical blank or sync. That seems a reasonable thing to do when you want to sync up to a video controller's output frame. What else but X would be setting up the VIA onboard graphics to do that?
