ICH4 will require very few lines of additional code. But basically the 
gpio dump function did not change much. Except now it also prints the 
register names. If those changed, older ICHs will need an additional 
register description, or they will print the wrong names.
No big magic.

I think we should not implicitly go with "all PCI IDs below this number 
follow the old scheme" heuristics, but instead add those ICHs that we 
checked explicitly. The infrastructure for doing that is quite in place.

Also, there's a mechanism to disable dumping for example the MCHBAR on 
those chipsets that don't have one.

But please, do test this and add the few missing lines to make it work 
on your chipset.
