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