The i810 chipset generally has two devices a
configuration via the PCI bridge and the device itself.
The chipset id is 0x71xx where the even number xx is
for the bridge and xx+1 is usually the device. But the
detection code for trying to incorporate all device
combinations is a little too difficult to incorporate.
A workaround is required to allow it detect all i81x
cards including i815s too since the basic architecture
for the cards is the same.
