From what I could see the older ICHs have PMBASE and GPIOs but no RCBA
for example. This should be fairly easy to handle. It might be safe to
add the PCI IDs from the i82801xx_lpc.c driver. For the in-firmware part
this tends to look different for different steppings of the same chip,
so we need to be careful there. The dumping utility is quite simple as
it doesn't need to know about chipset revision errata.
As long as you don't add the northbridge to the dumping functions, it
will bail out with a message like "this is not supported (yet) on your
