Side note - we already do have some quirks for the CK804 chipset, we 
probably just don't have enough (ie we have it for some HT stuff, but 
there are probably different ranges for ACPI etc other registers). 

I'm adding Brice Goglin to the Cc, since he was the one that created those 
quirks, which implies that he probably has access to documentation on that 
thing.

Brice: see the unfolding sad story on

which doesn't include Carlos' previous email, but does include my reply, 
so you can see what the resource allocation issue is..
