What exactly do you mean by 'it' ? The PCI device id ?

If they share the same device ID, then Bernhards patch is
really no better...

#define PCI_DEVICE_ID_VIA_P4X333 0x3168

In fact, P4X333 defines a chipset rather than a chip.
According to ..
http://www.viatech.com/en/apollo/p4x333.jsp and
http://www.viatech.com/en/apollo/p4x400.jsp ,
the northbridge is a VT8754 in both models, so the
correct define would seem to be PCI_DEVICE_ID_VIA_8754

Just to confirm, device 3168 is the host bridge in lspci output right?
And this does all work when you run a DRI application ?
