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

My experiments:
I changed two files:

usr/src/linux-2.6.11-rc5/include/linux/pci_ids.h
--- cut here ---
#define PCI_DEVICE_ID_VIA_8703_51_0 0x3148

#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
--- cut here ---

{ "vt6420", PCI_DEVICE_ID_VIA_6420, 0x00, 0x2f, VIA_UDMA_100 },          
         ; <= this i was add
{ "vt82c686b", PCI_DEVICE_ID_VIA_82C686, 0x40, 0x4f, VIA_UDMA_100 },
{ "vt82c686a", PCI_DEVICE_ID_VIA_82C686, 0x10, 0x2f, VIA_UDMA_66 },
--- cut here ---

But i was not successful :'-(
