Log:
ichsmb: try attaching only to intel hardware in the default case
Ideally we should attempt attaching only to known supported devices.
But I am not sure that we have all supported PCI IDs already listed,
and I am too young to die, err, I don't want to take the heat from
causing a trouble to someone.
MFC after: 1 week
X-ToDo: drop the default case
