That's about the size of it.  This is pretty near the bottom of my ever-shrinking
list of kernel drivers I care about.

That said, 12 years later, 16adf5d07987d93675945f3cecf0e33706566005
is still the right thing to do. Adding actual matches for the devices
rather than matching by class will prevent this getting loaded where it
doesn't need to be.

If someone actually cares to get this working, cargo-culting Oliver's
change to add the extra id is likely the way forward.
