872 This function returns true if the device passed to it is attached to an
873 ICH-ICH4. If the chip is not attached to an ICH, or is attached to an ICH5
874 or newer, it returns false.
875
876 This function determines which bridge it is attached to by scaning the pci
877 bus looking for bridge chips (hdr_type=1). When a bridge chip is detected,
878 the bridge's subordinate's secondary bus number is compared with this
879 devices bus number. If they match, then the device is attached to this
880 bridge. The bridge's device id is compared to a list of known device ids for
881 ICH-ICH4. Since many older ICH's (ICH2-ICH7) share the same device id, the
882 chip revision must also be checked to determine if the chip is older than an
883 ICH5.
884
885 To scan the bus, one of two functions is used depending on the kernel
886 version. For 2.4 kernels, the pci_find_device function is used. This
887 function has been depricated in the 2.6 kernel and replaced with the
888 fucntion pci_get_device. The macro walk_pci_bus determines which function to
889 use when the driver is built.
