Comment(by cjb):

 The X log contains "viaWaitVideoCommandFire: Timeout.", which comes from
 via_swov.c:

 {{{
     unsigned count = 50000;
     CARD32 volatile *pdwState =
             (CARD32 volatile *)(pVia->VidMapBase + V_COMPOSE_MODE);

     while (--count && ((*pdwState & V1_COMMAND_FIRE)
                        || (*pdwState & V3_COMMAND_FIRE))) ;
     if (!count) {
         ErrorF("viaWaitVideoCommandFire: Timeout.\n");
     }
 }
 }}}
