Not sure for addr mapping, but it's clear that it'll break any current snasphot.
They are also some devices embed in the chipset (sata controller,...). The whole architecture is very different that current chipset.

Yes (although that will be a pain to maintain :-/) 

There is also a new machine type called q35: 

see qemu-kvm/docs/q35-chipset.cfg 

seems to be incompatible with our addr mappings?
