Hello,
i trying resurrect this discussion again for solve this problem successfuly.

My experiments:
I changed two files:

#define PCI_DEVICE_ID_VIA_6420 0x4149                    ; <= this i was 
add
#define PCI_DEVICE_ID_VIA_XN266 0x3156
#define PCI_DEVICE_ID_VIA_8754C_0 0x3168

          ; <= this i was add

{ "vt82c686a", PCI_DEVICE_ID_VIA_82C686, 0x10, 0x2f, VIA_UDMA_66 },
--- cut here ---

But i was not successful :'-(
