Problems with VIA Apollo Pro Chipsets

I have a system using the Gigabyte GA-6VTXDR-C Motherboard which showed
the VIA Southbridge symptoms with our 3ware Escalade RAID Controller.
On heavy load (such as kernel compilation) i get random segmentation
faults on different places, not reproduceable but every now and then.

I noticed that the quirk_vialatency was not enabled, and modified
quirks.c accordingly - but this did not yet solve the issues :-(

Any idea? (except handing the system back to the manufacturer and
asking for a working system...)

Note for this patch: in the line above my addition, 0x3112 has now an
according definition in include/linux/pci_ids.h, so this "Not out yet"
could be replaced with the Chipset name:
#define PCI_DEVICE_ID_VIA_8361 0x3112
