We'd be happy to integrate support for it, but you should expect to
have to rework the patches to a form where they will be to our liking.

Your english seems to be quite sufficient so far, there are many
kernel developers who do not have english as main language. Ask if you
need something clarified when we reply to you.

Unfortunately, this patch alone doesn't do much good -- it just adds a
kernel config option without telling us much about what it's doing. It
would make more sense to also include the code changes that the config
option will result in (or makefile changes and c file additions, if
any).

In this case, isn't the southbridge just another PCI-e device? I don't
see how we would need a machine-specific configuration option to
enable it, but seeing the code changes that go along with it would
help explain to us.
