Well... looking at the driver source[0], I see the following comment:

 /* Xinerama has sync problem with DRI, disable it for now */
                if(xf86IsEntityShared(pScrn->entityList[0]))
                {
                    info->directRenderingEnabled = FALSE;
                    xf86DrvMsg(scrnIndex, X_WARNING,
                        "Direct Rendering Disabled -- "
                        "Dual-head configuration is not working with DRI "
                        "at present.\nPlease use only one Device/Screen "
                        "section in your XFConfig file.\n");
                }

So maybe I'll try a kernel with no DRI support. But that's going to suck in
different ways.

Edward.
