+ Only say N here if you have a I2O controller from SUN. The SUN

This should be detected at runtime, and that is easily done.
You can use the PCI device to get at the firmware device
node, and use that to look for a firmware device node property
that identifies it as a card from Sun.
Usually the "name" property has some identifying string in it.
Sometimes there is a property with the string "fcode" in it and you
could look for that as well.
