Hi, I noticed that a common motherboard manufacturer Micro-Star was missing it's PCI_VENDOR_ID and so I have sent this patch in. Later on I will send a patch to pci/quirks.c to unhide the SMBus on the M510C laptop once I have investigated it a bit more. It hides the SMBus the same as ASUS (and a couple of others) laptops. This is definately the correct ID, see http://www.pcidatabase.com/vendor_details.php?id=705 I would also be happy with PCI_VENDOR_ID_MICRO_STAR instead, what do you think?
