Comment(by gang65):

 Is this error exist only for VX800 chipset?
 Check revision of your VX800 chipset.

 I think this bug could exists because 3353A0 and 3353A1 (VX800) MMIO use
 Bar2.

 Please see VIAMapMMIO (via_driver.c file) in the latest VIA driver.


 Here is some source code from VIA
 {{{
 static Bool VIAMapMMIO(ScrnInfoPtr pScrn)
 {
     VIAPtr pVia = VIAPTR(pScrn);
     VIABIOSInfoPtr  pBIOSInfo = pVia->pBIOSInfo;
     vgaHWPtr hwp;

  DEBUG(xf86DrvMsg(pScrn->scrnIndex, X_INFO, "VIAMapMMIO\n"));
         /*3353A0 and 3353A1 MMIO use Bar2*/
         if ((pVia->Chipset == VIA_VX800) &&
                 (VIAGetRevisionOfVX800() == REVISION_VX800_A))
         pVia->MmioBase = MEMBASE(pVia->PciInfo, 2);
         else
             pVia->MmioBase = MEMBASE(pVia->PciInfo, 1);


 }}}
