945 This function returns true if the device passed to it is attached to an
946 ICH-ICH4. If the chip is not attached to an ICH, or is attached to an ICH5
947 or newer, it returns false.
948
949 This function determines which bridge it is attached to by scaning the pci
950 bus looking for bridge chips (hdr_type=1). When a bridge chip is detected,
951 the bridge's subordinate's secondary bus number is compared with this
952 devices bus number. If they match, then the device is attached to this
953 bridge. The bridge's device id is compared to a list of known device ids for
954 ICH-ICH4. Since many older ICH's (ICH2-ICH7) share the same device id, the
955 chip revision must also be checked to determine if the chip is older than an
956 ICH5.
957
958 To scan the bus, one of two functions is used depending on the kernel
959 version. For 2.4 kernels, the pci_find_device function is used. This
960 function has been depricated in the 2.6 kernel and replaced with the
961 fucntion pci_get_device. The macro walk_pci_bus determines which function to
962 use when the driver is built.
