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);
}}}
